Liosomadoras oncinus - Jaguar http://diszhal.info/english/catfishes/en_Liosomadoras_oncinus.php

 Scientific name: (Jardine; 1841)  Common name: Jaguar catfish Group:  Habitat: South America; Rio Ucayali (Peru), Rio Xeruiuni, Rio Negro (Brazil) Size: 25 cm  Biotope: Inhabits in large rivers, streams, lakes and flooded areas.  Social behavior: Twilight-active, gregarious fish which is suitable for the community aquarium. Can be kept with fishes over 5 cm long. Generally peaceful and shy, but territorial.  Diet: Carnivorous; live foods of all kind, fish. Juveniles prefer tubifex. Add food after lights out.  Breeding: Has not bred in an aquarium. Tank: Minimum 200 litres  Population: 2-3 fish for 300 litres  Decoration: Tough vegetation using Echinodorus species, roots and large stone constuctions as hideouts. It does not like bright lights, so dim lighting and floating plants are appreciated.  Temperature: 20-28 °C pH: 4,8-7,2 Hardness: 1-15NK° Lifespan: 8-12 years Description: The base color of the fish is light-brown, with darker blotches on it. They get their commin name from their body pattern. The fins are also spotted. The body is short and the head is large and broad. It has a distinct yellow lateral line. During the day they usually stay in their caves, and fiercely defend it against intruders. It is possible to house several Jaguar catfishes in the same aquarium if it is large enough. There must also be plenty of hiding spots throughout the aquarium. The male has the urogenital papilla at the anterior edge of the anal fin, and more brightly colored. Mature males are also develop thicker dorsal and pectoral fins. Eggs are fertilized internally, similar to Auchenip- terus, and are immediately thereafter expelled. The spe- cies has not bred in an aquarium. President C.A.R.E.S.

Our October meeting featured Ken Boorman, giving a very informative talk about invasive species. Quite an eye opener to realize there are so many. I’m looking forward to our November meeting when we will have Al Ridley giving a talk about Barbs. The jar show will be Cichlids – substrate spawning (eg, Angels, Kribs, Rams etc.) and mouth-brooding (e.g. Guentheri, Aulonocara …), the CARES fish as well as the usual open fish and plant categories. We will have our mini auction at the meeting, so bring in any extra fish, plants or aquaria related things Lest We Forget you wish to sell. Anyone wanting to find out what we’re all about is welcome to attend. Looking forward to seeing you all there. Eric Gessinger P resid ent London Aquaria Society

Moss Bryozoa

http://naturalaquariums.com/inverts/mossanimals.html

Moss animal is the common name for Bryozoa. Most of the known 3,500 species of moss animals are marine species but there are also about 50 freshwa- ter species. Some of those will sometimes appear in the home aquarium. Moss animals live in large colonies and resemble a mass of very small ma- rine feather dusters. Individuals in the colony are called zooids. The have small hair like tentacles that retract when they are disturbed. The tentacles bring food to the animals. They eat algae and protozoa. Moss animals may show up in the aquarium occasionally, unfortunately I've never been able to keep the colonies alive more than a few months at a time. They will sometimes show up on a somewhat regular basis in the same tanks. The moss animals I see most often in my aquariums form branching colonies, though other speices form different types of colonies. Some very large colonies that look like a gaint egg mass are found in some lakes. The photo shows moss animals in one of my aquariums. The zooids pictured have produced statoblasts. This is an asexual form of reproduction. Statoblasts, are somewhat similar to seeds in plants. They are resistant to adverse conditions and can germinate to form a new colony when conditions improve.

London Aquaria Society 3 Horned Nerite Snail A GUIDE TO HORNED NERITE SNAILS https://aquariuminfo.org/hornedneritesnail.html Horned Nerite Snails are a tropical freshwater species of aquarium snail. They are easily identified by the multiple dark horns that protrude from their shell. The shell is yellow in color with thick black swirls along the edge. They are popular algae eaters and debris removers. Most notably they will keep your glass crystal clear. They are available to purchase at most LFS or from other hobbyists. Horned Nerite Snails are popular and pricier than other snails because they are impossible to breed in freshwater. Nerite snails can grow up to 1" but adults are more commonly found between 1/2 and 3/4" in size. Horned Nerite Snails can also be used in out- door ponds for similar purpose. Horned Nerite Snails are avid consumers of aquarium algae and are useful in keeping the nitrates under control in an aquarium. They will keep the glass and substrate relatively clean, aiding the water changing and substrate vacuuming process. Horned Nerite Snails are peaceful creatures. They can be kept with other non aggressive fish, snail and shrimp species without problem. Horned Nerite Snails are known as a species of 'tidal snail'. The name comes from the ability of the snail to live out of the water for prolonged periods of time. Unfortunately it is not uncommon for Horned Nerite Snails to escape. They are fairly easy to find and can be picked up and placed back into the aquarium. It is en- couraged to keep a daily eye on Horned Nerite Snails

Temperature: 75°F The optimum aquarium temperature for Horned Nerite Snails is around 70°F - 80°F (21°C-27°C).

pH: 7 | Hardness 7 - Horned Nerite Snails require pH between about 6.5 and 8. Relative wa- ter hardness for Horned Nerite Snails should be in the range of 6-12dH. Horned Nerite Snails are hardy species and are able to withstand captivity fluctuations.

London Aquaria Society 4 Horned Nerite Snail A GUIDE TO HORNED NERITE SNAILS

Max. Size: 1" Horned Nerite Snails can grow up to 1" but are often found at a maximum size of 3/4". They are suitable for medium sized aquariums. Nitrite 0ppm: Nitrite should always be 0. Ammonia 0ppm: Horned Nerite Snails are sensitive to ammonia spikes. Nitrate>40ppm: Nitrates should be as close to 0ppm as possible. Horned Nerite Snails consume debris contributing to lower nitrates. Stocking Guide: Horned Nerite Snails are excellent at consuming debris and algae. However in large numbers they will require extra food. For this reason it is wise to stock no more than one snail for every 4 gallons of aquarium water. Horned Nerite Snails have a short captive life of approxi- mately one year. For this reason it is wise to slowly re-purchase snails throughout the year as Horned Nerite Snails cannot reproduce in freshwater. Feeding: Horned Nerite Snails can simply be fed commercial flake and pellet food. They only require supplemental feeding if there is no debris or algae left to consume. They are efficient cleaners and will leave the glass and substrate very clean. They are not fussy eaters. The filter should be turned off during feeding to allow the food to float to the substrate where it is easily accessible for the Horned Nerite Snails. Breeding: Horned Nerite Snails will not breed in freshwater aquariums. Horned Nerite Snails will only breed in brackish waters and even then raising young is difficult. Young successfully raised in captivity have far lower life expectancies than those wild caught. On the upside, Horned Ner- ite Snails will not overpopulate the aquarium making them far easier maintenance than other species .

London Aquaria Society 5 The Fish With “four eyes” https://creation.com/ the-fish-with-four-eyes-anableps (Anableps)

One of the strangest fish in the world is Anableps an- ableps, commonly called the ‘four-eyed fish’ because of the unique configuration of its eyes.1 These are large and bulging, like those of a frog, and are located on the top of its head so that it swims with its eyes half in and half out of the water. At the waterline, the eyes are divided by a band of epi- thelium (tissue) into upper and lower parts, with separate cor- neas and retinas, which function for aerial and underwater vi- By: Russell Grigg sion respectively.2,3 The lens is more egg-shaped than convex and can focus two images simultaneously, one from above the water and the other from below (see diagram). This means that the fish’s two eyes actually function as four eyes; hence its name. When Anableps is looking out into the air, the light rays pass through the shorter width of the lens, which gives good distance vision for locating its prey of insects; it also means that the fish is difficult to catch, as it can see fishermen approaching! From under the water, the light rays pass through the full length of the lens, so that the fish is near-sighted under water.4 One is reminded of a bifocal lens in spectacles. This configuration of the eyes enables Anableps to search for food in one habitat (air) and at the same time watch out for predators in another habitat (water). When it sees a predator approaching through the wa- ter, it escapes by leaping out of it, which is a reason why this species is not very suitable for keeping in a small home aquarium. Another unusual habit is that when swimming it continually ducks its head under the water. This is because, unlike most land animals, it does not have a tear duct to keep the eye moist and so must duck to prevent its eyes from drying out. How the eye of the four-eyed fish works So, is the four eyed fish evidence for evolution or creation? The Encyclopaedia Britannica describes An- ableps as ‘an extreme example of adaptation to life near the air-water interface’.5 If this is the case, how did it develop its multi-functional eyes, beginning as an ordinary fish with normal, single-function eyes? It is extremely difficult to see how something as complex as this could develop by gradual stages, and the more parts that have to develop, the greater the difficulty. This includes the complex brain setup needed to simultaneously decode the double images being received by the two retinas. How did all this evolve until it was fully functional? There is, in fact, no evidence that Anableps evolved. By far the simplest explanation of the evidence is that Anableps was created on the fifth day of Creation Week by the Lord God, who created ‘every living creature that moveth, which the waters brought forth abundantly, after their kind’ (Genesis 1:21). This accounts for the formation of all the parts of the eyes and the needed complementary parts of the brain, with everything functional from the beginning.

London Aquaria Society 6 Subwassertang Plant

www.everythingaquatic.net/forum/articles/aquatic-plant-library/149872- subwassertang Created by: AmazonPassion Published: 03-12-2013, 07:12 PM

Editor’s Note: I was on the Facebook page for the Club and noticed Tracey asking if anyone in Canada had the Subwassertang plant. I’d never heard of this plant before so I thought I would do some research.

Common Names: Subwassertang, Round Pellia, Freshwater seaweed. Latin Name: Lomariopsis sp. Family Name: Lomariospidaceae. Plant Form: Fern Gametophyte. Sold as: Portion. Placement: Foreground. Max Size: Leaf (thallus) Height: 2.5 cm (1 inch), Leaf (thallus) Width 0.5 cm (0.2 inch). Planting: Tied to hardscape or left on the bottom of the tank. Flowers: No. Photographer: kinezumi89 Propagation: Cuttings. Growth Rate: Medium Originates From: Asia True Aquatic: Amphibious. Plant Care pH: 5-7.5 Supplements: Balanced water column fertilizers. Recommended Tank Size: Any, great for small/invert tanks. Care Level: Easy. Good for Beginners: Yes Subwassertang (Round Pellia) often confused with Pellia but the Subwassertang has a translucent green thalloid and feels like seaweed. The thalloids grow in a nice stratified pattern, once estab- lished on hardscape. You can simply place Subwassertang in the bottom of the tank or tie it to a driftwood/rock and watch it grow. Grows both in low and high light. Does not do well in tanks that are dose with Excel. Propagation: Simply cut leaves.

London Aquaria Society 7 Long-Term Impacts of the Invasive Round Goby Neogobius melanostomus on Fish Community Diversity and Diets in the St. Clair River, Michigan

Thesis · December 2013 with 260 Reads Thesis for: MSc, Advisor: David Jude Cite this publication Erin Burkett Abstract

Round gobies (Neogobius melanostomus) were first documented within the St. Clair River in 1990, and subsequently impacted native benthic fishes, including sculpins and darters, through direct predation and competi- tion for space and prey. In order to identify long-term impacts on fish species associated with the round goby in- vasion in the St. Clair River, Michigan, I compared fish community composition and diet overlap between round goby and native species in 1994 with similar data from 2011. All fish were collected by trawls (3-, 5-, 7-, 9-, 11-m depths) and seines (1 m) in May, July, and September 2011, and compared to similar data collected in May, June, and September 1994. Catch-per-unit effort (CPUE) for rainbow darter (Etheostoma caeruleum) and round goby significantly decreased in the nearshore zone between 1994 and 2011. In the offshore zone, relative abundance of northern madtom (Noturus stigmosus) decreased sig- nificantly between 1994 and 2011, while round goby relative abundance both increased and decreased, depend- ing on month. CPUE of channel darter (Percina copelandi), johnny darter (Etheostoma nigrum), mottled sculpin (Cottus bardii), and round goby also significantly decreased in the offshore zone between 1994 and 2011. There was significant diet overlap between round gobies and native rainbow darter in 1994, suggesting diet overlap and competition for food contributed to rainbow darter population declines in the St. Clair River from 1994 to 2011. However, significant diet overlap was also found in both years between round goby and other native species that did not decline from 1994 to 2011. In 2011, round gobies showed significant diet overlap with rock bass (Ambloplites rupestris) in the nearshore zone, and significant overlap with logperch (Percina caprodes) and trout-perch (Percopsis omiscomaycus) in the offshore zone. In 1994, reliance on zebra mussels (Dreissena polymorpha) by adult round goby prevented frequent signifi- cant diet overlap from occurring between large round gobies and native species that could not consume zebra mussels, but in 2011, round gobies, log perch, and trout-perch all consumed quagga mussels (Dreissena bugensis). These results suggest that differential foraging strategies allowed some native fish to forage without compe- tition from round goby, and that the nega- www.researchgate.net/publication/265336321_Long- tive impacts of the round goby invasion and Term_Impacts_of_the_Invasive_Round_Goby_Neogobius_melanostomus establishment on fish species diversity within _on_Fish_Community_Diversity_and_Diets_in_the_St_Clair_River_Michi the St. Clair River may be isolated to a few gan species, and due to competition for other resources, such as space. Establishment of the round goby within Great Lakes tributaries, nearshore environments, and more recently the Mississippi River basin will likely have differing impacts on native fish communities based on the pre-existing communities, other environmental stressors, and foraging habits of native fishes.

London Aquaria Society 9 Mystery of “alien pod” solved: Colony of freshwater gryozoans

https://www.sciencedaily.com/releases/2010/11/101101142517.htm Date: November 1, 2010 Source: Virginia Institute of Marine Science

Summary: Researchers in Virginia have identified an "alien pod" discovered in a local freshwater lake as a very large colony of freshwater bryozoans -- aka "moss animals." Bryozoan: This freshwater bryozoan was found in the lake in City Center at Oyster Point (Newport News). Bryozoans are filter feeders that live in encrusting and branching colonies, mostly in seawater. This colony is about 4 feet in diameter; most colonies of marine bryozoans occur as thin sheets. Tracy Collier, an employee at Home Technologies in City Center at Oyster Point, was walking her em- ployer's Westie around the Center's manmade lake on Thursday when she saw a large, mysterious blob floating in the water. Co-worker Charlie Schmuck says: "The lake is behind our office. Tracy was walking by the lake, saw the object, and asked everyone else to come out and take a look." Tracy thought it was "a huge dead snake." Char- lie thought it "looked like some weird underwater fungus, like the ones that explode when you poke them." Perhaps because it was just a few days before Halloween, co-worker Dale Leonart's initial guess was that "it has to be an alien pod." After further consideration, he thought it might be some type of sponge. Hoping to solve the mystery, Charlie took some pictures of the object and e-mailed them along with a description to the Virginia Institute of Marine Science in Gloucester Point. The scientists at VIMS were equally intrigued. The e-mail read: "The object is about 4 feet in diameter. It has moved about 6 feet down the shoreline in the last 24 hours. It 'jiggles' when the waves in the lake hit it… when we prod it, it seems to be spongy feeling… The texture appears to be that of a rock with algae spots on it -- it is brown and yellow, with a pattern of some type." A brief flurry of internal e-mails fol- Credit: Photo submitted by Mr. Charles Schmuck lowed. The marine tunicate Eudistoma hepati- cum? Unlikely, as the lake contains fresh water. A Halloween prank in which someone moved a marine organism to the lake? Perhaps. The final consensus was that the organism is Pecti- natella magnifica -- the "magnificient bryo- zoan." Bryozoan: This freshwater bryozoan was found in the lake in City Center at Oyster Point (Newport News). Bryozoans are filter feeders that live in encrusting and branching colonies, mostly in seawater. This colony is about 4 feet in diameter; most colonies of ma- rine bryozoans occur as thin sheets.

London Aquaria Society 10 Mystery of “alien pod” solved: Colony of freshwater gryozoans cont’d from page 10

"Moss Animal s" That identification is itself somewhat surprising, as the vast ma- jority of bryozoans -- thousands of species -- live in salt water. Marine bryozoans are common but inconspicuous filter feeders that grow in thin, encrusting colonies atop rocks, kelp blades, shellfish, and other hard objects. When the individual animals extend their tentatcles to feed, the colony takes on a fuzzy appearance, hence the bryozoans' common name of "moss animal." Although individual bryozoans are built on a simple plan -- a U- shaped gut inside a bag-like body with no lungs or gills, and no circula- tory or excretory system -- they are true survivors, with a fossil record that dates back some 500 million years. Freshwater bryozoans are far less diverse than their marine cousins, with only about 50 species world- wide, but what they lack in numbers they make up for in size -- like the 4-foot blob found floating in Newport News. The City Center blob is actually much larger than most reports for the species, which put a large colony at only 1-2 feet across. Colonies of Pectinatella magnifica feature a surface layer of adjoining "rosettes" -- each with 12-18 animals or "zooids" -- around a central jelly-like mass that is 99% water. The colonies can be free floating or attached to a piling or other submerged object. One study even showed that young colonies of P. magnifica can actually move on their own by coordinated pulsing of the individual animals. VIMS professor Carl Hershner notes that bryozoans consume algae, so the "alien pod" is "actually a good thing to have around, despite its looks." "It's not a sign of bad water quality," he adds, "and it doesn't hurt fish. It can clog pipes, though, and it will be smelly if it's removed from the water."

London Aquaria Society 11 African Water Fern (Bolbitis Heudelotii)

Submitted by: Glen Hawkins, November, 2018, London Aquaria Society The African water fern is a true aquatic plant species, that can be found in various small lakes, rivers and streams in South Africa. It's unique leaves can range from bright to dark green and provide an attractive con- trast to other aquarium plants. This plant is considered to be a slow growing plant species, but once acclimated, it’s growth rate can in- crease dramatically. It is also an easy to care for plant that likes to be in the water flow of a power filter and can grow in low light conditions. Even so, its growth can be increased in a medium to high light tank. The African water fern has no special nutrient or C02 requirements. Adding additional C02 or liquid fertil- izer would only make small increases in growth. This plant can make a great focus point background or rear cor- ners in an aquarium, as well as providing great shelter for fish inhabitants. The rhizome of this plant should not be buried in the substrate but rather tied to wood or rock with cot- ton thread or fishing line. Attached in the same way that anubias or java fern plants would be attached. Eventu- ally, the plant will anchor itself with little tiny roots to the wood or rock. Propagation of this plants is relatively easy and is done by dividing the rhizome with very sharp sterilized Thanks again Glen scissors or knife. The new plants that grow from propagation make a bright green contrast while the older lar- ger plants are dark green. For maintenance, old, damaged or dying leaves can be clipped off at the base of the leaf which will keep the plant both in check for size and in prime health. I find that these plants can make great eye catching show stoppers once large and mature and look amaz- ing in medium to large aquariums.

MEDIA RELEASE Thursday, October 25 th, 2018 CAOAC addresses Aquatic Animal Antibiotic Use The Canadian Association of Aquarium Clubs (CAOAC) has been in- formed by Health Canada, that a new piece of legislation will take effect on De- cember 1 st, 2018, that could have an impact on the fishkeeping hobby. The ruling titled, “Responsible Use of Medically Important Antimicrobials in Animals”, will require indi- viduals to obtain a prescription for purchasing medically important antibiotics for all animals, including aquatic animals. The purpose of this ruling is to prevent the emergence and spread of antimicrobial-resistant infections caused by over usage of antimicrobials in veterinary medicine and in the agriculture industry. “The Canadian Association of Aquarium Clubs” , formally supports Health Canada’s ruling on this matter, as our mission is to teach members that good animal husbandry will help to prevent illness in our fish,” said President of the Canadian Association of Aquarium Clubs, Nancy Egelton. Before this ruling, there were no guidelines or rulings for fish medications. In addition, there were no guidelines on dosages and medications used on humans were being purchased and used on aquatic animals. 80% of animal antibiotics used in Canada are non-prescribed and are causing animals to become immune to illnesses through the over usage of these antibiotics from their owners. “To comply with this ruling, we (CAOAC) must learn to modify our way of thinking and our use of medi- cations for fish. We will be researching further to find veterinarians that will help us to correctly medicate our fish.

Informal CAOAC meeting minutes October 25, 2018 Location, KWAS Octoberfish Show

Attendees: Nancy Egelton, Peter DeSousa, Scott Vanderfleet, Phil - St. Catherines, Cindy St. Catherines Peter Melady, Barry-Durham, Myron-Durham, Anne Marie Towell, TCGG-via facetime. This was a non-Quorum meeting, so it was conducted as an informal drop in talk to several club mem- bers. We had several people stop by and just listen or chat a bit. It was a great experience. We started off the meeting by talking about using my IPHone to tether the ipad and we used my data to converse with Ann Marie by video, it worked perfectly and used virtually no data. It was an experiment as an alternative to the fire stick, which was not available. We talked about the Heath Canada ruling and how to word the media release. We compiled all the ideas and the facts and the statement will be supplied to all clubs for print in their newsletters. We will look into how we can contact a fish Vet to obtain antibiotics over the next few months, as the Veterinary community itself is just now compiling this information. We will make the press release available to be in all the club newsletters and on the website for CAOAC. The original document from Health Canada will be published. Club insurance due date was talked about. We have a chance to obtain a grant for some sort of community service. The idea of local club fish res- cues has been talked about. We may need to have a contest to pick a catchy name for our new local club fish rescue. This is some- thing that each club can easily do. More information will be talked about at the next meeting.
