Cichlid, at the moment. Do you know if casually it was in a Madagascan exhibit? That would help...

Nope it is in a tank in which all the species are from South America!

I suggest one of the Heros species (related to the well known severum H.severus). But this is not my field of expertise and I can't look it up because I donated my books about American cichlids to Chester Zoo's library

Chiseltooth cichlid, Theraps bocourti

Agree with Chiseltooth cichlid.
