I just got 2 electric blue haps and 2 lemon yellows for my 46g tall. The saleperson stated that they like to eat some sort of vegetable pellets rather than ordinary cichlid pellets. I got what he suggested and also some African Cichlid "attack" sinking pellets. What should I be feeding these guys? Also Is that about the limit for this tank? I have 4 africans, a birchir, eel cat, and a pleco. I would like a surface fish for the tank to fill the top part is there anything?
