I was glad to see a lot of you there. Many hands made light work, so thank you to all of the members who volunteered to assist in set- up, take down, running or any other odd jobs, it was greatly appreciated. The auction is also a great way for those high school students to get some volunteer hours. The speaker for April was Larry Johnson. Larry did a great talk about his recent trip to Africa, and the work they do to help with conservation. It was good to see so many people come out. Thanks to Larry for doing the judging. The guest speaker for May will be our very own Dorothy Reimer. Dorothy will be giving a talk about aquar- ium plants. As I am sure you all know, Dorothy is well known in the hobby around the world, for her exper- tise in horticulture. The fish show for May will be in mouth brooding cichlids (Guentheri, Aulonacara, etc), open fish class as well as the open plant class. To help all of those that are new to the hobby we will be having a new class “pairs”. This new class will be held in May and again in the fall. This class will be for a male and female of any type of fish. This will be a great way for everyone to May 24th week-end CAOAC Convention get to know the difference between the sexes of fish. There will be a ten dollar gift certificate for this class. The auction will be there as usual. Hope to see all of you there We have extra shirts available for $10.00 each which will be available Ron Bishop President at our next General Meeting & Auction on May 2, 2010. The London Aquaria Society is a non-profit organization, established in June 1956. Its main objective is to promote interest in breeding and raising tropical fish and also to provide a means through which hobbyists may exchange ideas, gain information and display their fish, sharing them in the public in the London Area.

A foul smell in a culture indicates that anaerobic conditions prevail: favouring the growth Protozoa: Polystomella of anaerobic bacteria which produce hydrogen sulphide. If this is noted, the culture should be stirred more frequently or mild aeration applied for a while. Remember that infusoria need oxygen and anaerobic conditions will impede their growth and multiplication. Many infusoria cultures fail because of too low a temperature so this point should be checked also. Successful fish breeding commences with learning to produce good thick cultures of infusoria. The final product should be virtually as clear as aquarium water and teeming with thousands of organisms. The trained eye can see them clearly if a glass jar full of culture is held so that light strikes from outside. A hand lens giving about five power magnification is useful but the magnification given by even a low power microscope is too high to enable one to assess the strength of the culture.
