6 months back I got a few fish (1/2") that I bought off craigslist as demasoni. They later developed a yellow on their top fin and tail, but they were still young so there were many guesses. Please let me know what you think now that it's larger (2.5"). I still think it's a demasoni hybrid of some kind.

The pictures are of the most dominant male. His aggression is something fierce. I removed a dominant demasoni from my main tank that was causing issues and placed him with this fish. Within 2 hours, the pure demasoni was shredded and dead.

His head has developed some orange color lately.

Hmm could be a hybrid. It seems odd that the yellow showed up later.

I have 2 guesses.
Yellow Top Mbamba, or Labidochromis sp. "Mbamba"

Some type of Cynotilapia afra species. Many of them look a lot alike. Chewere or Chimate.

I think it's more likely the Labidochromis sp. "Mbamba". Which is odd, not many fish can stand up to a demasoni let alone kill one.

I agree...Yellow fin mbamba

Mabey Afra Yellow Blaze....Since you said he has some color on his head

it does look like a mbamba but the vertical stripes are looking just like some kind of demasoni hybrid..cool fish either way

Labidochromis sp. "Mbamba" is the closest guess. Not a Cynotilapia species.
