And I agree with Mike. I don't have all the Tropheops down any more. But if I recall there are ~3 that match fairly well. (Maybe they were called Tropheops tropheops, Tropheops Sand (Undu Reef), Tropheops novemfasciatus (Kadango)) But honestly I can't remember the mouths right to say.
And I am sure. But feel free to do more searches. This is a very common fish in the hoby so it turns up all over. When they are young they are very red/orange, but as the get older bigger they get to look more like yours (and whiter).
