Hi everyone! For once I finally have a tank large enough to reasonably house a pair or trio of apistos - namely, a 20 high. However, I really don't know much about these fish or cichlids in general when I think about it (my experience being limited to a disastrous 2 week stint with a pair of bandit cichlids I tried to keep in a 20 long to themselves...they were quickly returned), so I have a question about them...do they have any need for dither fish, either as targets for aggression or to coax them out of hiding? If so, what are some good dither fishes that are themselves not too demanding? I am fortunate to have 50 ppm tds, almost zero KH and GH tap water at my disposal, so I could easily keep a hardier apisto like borellii or cacatuoides. Thanks
