the 2nd is impossible to see lol, the last is a bit small to sex and i cant see the stripes to tell what it even is.
the first looks like a male kenyi (as long as its more yellow than blue), but the stripes seem a little wierd imo.
the 3rd i think is a female red zebra purely because it appears to be deep orange and rounder, plus the fins are not tall like the males usual fins.
the lab is probably female due to lack of black on bottom fins, but sexing cichlids is very difficult in alot of cases and the photos are too distant to get a good impression.
which one is dominant? do any shimmy when around other fish? what breed is the last fish? xxx
