hey everyone, made my first foray into clown loaches...very happy with the decision. Currently I have 7 small loaches (2-4 inches) in a 30 gallon grow out with a few silver dollars. Everything seems to be going well, good appetites, lots of activity...at what point should I move them to a 75 gallon grow out? I don't want to mess up a good thing, but I also don't want to stunt growth. Thoughts?
