WHy dont you get a tank seperator?

I have a yellow lab and a sunshine peacock both holding for about 4 weeks now and still haven't released yet. I just left them in their tank and let nature take it's course. Survival of the fittess

Um I have 5 total holding.... I am pretty new at this, So I am sure I will figure out what works best one day.

this blue cichlid, what type of cichlid is it?

It is a Pseudotropheus zebra. But there are so many variations tthat I am not real sure about.
