Thanks, I'll get the small then.
I'm just getting the spirulina based pellets to feed to it once, maybe twice a week. I keep reading that spirulina is important to feed them, but I just recently read something saying that feeding too much spirulina has been linked with black spots on cichlids. So I don't want it to be in their staple diet, better safe than sorry.
Thanks for the advice. When you say cook, do mean boil? I tried feeding it a slice of cucumber the other day, and it was scared of it, haha. It was pretty cute, I'll have to put in a smaller piece next time.
