I have 3. They were cheap. The guy said that they were all males and he said that males get more colorful. I got them from LiveFishDirect. They did not have any aquariums. They just kept all of the small fish in a bunch of utility sinks. They had probably 100 sinks. I am going to wait until he gets better. I have some medium pellet cichlid gold and i have not seen them eat. I also got another pleco and 2 apple snails while i was there. I will probably move the electric blues into the 55 once i get the shipping container and get the 55 out there. I will then move my 20 and then both of my 40s. Then i will build a rack to hold an additional 6 40s and i decided that i am going to hold off on buying a used tank and build a plywood tank instead.
