I have a 100 gallon tank I had a accident and lost most of my fish(dont ask long story) I was left with only 2 little catfish and a lemon yellow (yellow with a black stripe on its top fin.) I got yesterday a peacock but all my fish stay near the bottom of the tank unless its feeding time. I know that differnt fish like certian parts of the tank. Is this true also for Cichilds? If so what can I get that will stay near the top of the tank?
