I was offered this 20 gallon hex tank. I planned on putting my Black Convict pair in it but was told they wouldn't have enouh room. I dont have any experience with a Hexagon tank so what could I put into it if I can't use it for my convicts?
It's not a bioload issue as 20 gallons at bare minimum is enough for two cons. The issue is side to side swimming. It wouldn't be horrible and I have seen people do it, but a 20 long is usually preferred. If you have nothing else you could do it though.
