Tropical Fish Now That You Have Set up Your Aquarium and Are Starting to Think About Adding Fish, You Have Many Choices to Choose From
Tropical Fish Now that you have set up your aquarium and are starting to think about adding fish, you have many choices to choose from. One specific type of fish is the tropical fish, found in tropical waters all over the world and in areas near the equator. They can live in fresh water such as ponds, lakes, streams and even oceans that are salt water. In home aquariums, tropical fish are usually kept in heated fish tanks or in areas where the ambient room temperature is between 70°F - 82°F. As you make your decisions, be sure to research their compatibility, hardiness and if they are a schooling fish or not. Selecting the right fish will help ensure that you have hours of enjoyment and success. Today, many freshwater fish are captive bred either in fish farms or by hobbyists, making them readily available and easy to find. Popular freshwater tropical fish include Bettas, Guppies, Tetras, Swordtails, Platys, Barbs, Mollies and Corydoras among others. Sometimes people starting out in the aquatic hobby may not always provide their fish with ideal living conditions. Fish recommended for beginners and new aquariums must be durable and able to handle sometimes-poor water quality and stressful living conditions. The list included here are freshwater fish and will provide you with a nice assortment to consider. Cold -Water Fish The most common cold-water fish species is the goldfish but there are many other fish species that do not require a heated tank such as White Cloud Mountain Minnows, Bloodfin Tetras, and Rosy Barbs among others; where their preferred water temperature is between 64 to 72 degrees F. -

Amazon Alive: a Decade of Discoveries 1999-2009
Amazon Alive! A decade of discovery 1999-2009 The Amazon is the planet’s largest rainforest and river basin. It supports countless thousands of species, as well as 30 million people. © Brent Stirton / Getty Images / WWF-UK © Brent Stirton / Getty Images The Amazon is the largest rainforest on Earth. It’s famed for its unrivalled biological diversity, with wildlife that includes jaguars, river dolphins, manatees, giant otters, capybaras, harpy eagles, anacondas and piranhas. The many unique habitats in this globally significant region conceal a wealth of hidden species, which scientists continue to discover at an incredible rate. Between 1999 and 2009, at least 1,200 new species of plants and vertebrates have been discovered in the Amazon biome (see page 6 for a map showing the extent of the region that this spans). The new species include 637 plants, 257 fish, 216 amphibians, 55 reptiles, 16 birds and 39 mammals. In addition, thousands of new invertebrate species have been uncovered. Owing to the sheer number of the latter, these are not covered in detail by this report. This report has tried to be comprehensive in its listing of new plants and vertebrates described from the Amazon biome in the last decade. But for the largest groups of life on Earth, such as invertebrates, such lists do not exist – so the number of new species presented here is no doubt an underestimate.

PAIR BOND DYNAMICS: EVALUATING LONGITUDINAL CHANGES IN BEHAVIOR AND 11-KETOTESTOSTERONE IN PARENTAL CONVICT CICHLIDS (AMATITLANIA SIQUIA) By CELINE RICHARDS Under the Direction of Edmund Rodgers, PhD ABSTRACT Bi-parental care and pair bonding often coincide in nature. The reproductive success of the organisms that apply this strategy is dependent upon defensive behaviors and territorial aggression. Some of these organisms also display affiliative behavior within the pair pond during the time of parental care. The behavioral dynamics that occur over the course of the pair bond and their relationship to the reproductive success of the organism is not well understood. Convict cichlids (Amatitlania siquia) form pair bonds during the breeding season and provide bi- parental care; their behavioral repertoire is ideal for studying pair bonding. The androgen profile of organisms that provide parental care through aggressive means is also not fully understood. -

Celestial Pearl Danio", a New Genus and Species of Colourful Minute Cyprinid Fish from Myanmar (Pisces: Cypriniformes)
THE RAFFLES BULLETIN OF ZOOLOGY 2007 55(1): 131-140 Date of Publication: 28 Feb.2007 © National University of Singapore THE "CELESTIAL PEARL DANIO", A NEW GENUS AND SPECIES OF COLOURFUL MINUTE CYPRINID FISH FROM MYANMAR (PISCES: CYPRINIFORMES) Tyson R. Roberts Research Associate, Smithsonian Tropical Research Institute Email: [email protected] ABSTRACT. - Celestichthys margaritatus, a new genus and species of Danioinae, is described from a rapidly developing locality in the Salween basin about 70-80 km northeast of Inle Lake in northern Myanmar. Males and females are strikingly colouful. It is apparently most closely related to two danioins endemic to Inle, Microrasbora rubescens and "Microrasbora" erythromicron. The latter species may be congeneric with the new species. The new genus is identified as a danioin by specializations on its lower jaw and its numerous anal fin rays. The colouration, while highly distinctive, seems also to be characteristically danioin. The danioin notch (Roberts, 1986; Fang, 2003) is reduced or absent, but the danioin mandibular flap and bony knob (defined herein) are present. The anal fin has iiiSVz-lOV: rays. In addition to its distinctive body spots and barred fins the new fish is distinguished from other species of danioins by the following combination of characters: snout and mouth extremely short; premaxillary with an elongate and very slender ascending process; mandible foreshortened; body deep, with rounded dorsal and anal fins; modal vertebral count 15+16=31; caudal fin moderately rather than deeply forked; principal caudal fin rays 9/8; scales vertically ovoid; and pharyngeal teeth conical, in three rows KEY WORDS. - Hopong; principal caudal fin rays; danioin mandibular notch, knob, and pad; captive breeding. -
