hi,
i love keyholes, they were the first cichlids i kept and along with the ram got me into cichlids. they are a very peaceful fish and imo do much better in pairs or trios. gives them more confidence being with their own kind
Yes, get 3 keyholes 2 male 2 females. (Male has long top and bottom fins stretched down to they end fin) i had 4 and one got left out so 3 would probably best but i rehomed mine as i am now with discus.
