Came back to say it could also be a chocolate cichlid, but I will also add that the stomach shouldn't be that concave regardless of what it is, and you shouldn't be able to see the definition of the crest of the skull. That is not a "unique" fish, that is a sick fish. If it's been like that over the last two months, then yes, it's dying. Looks like TB I've seen in other CA cichlids. They'll act the same, eat readily, I've even had a cutteri that was wasting away like that lay eggs. And then they die. Can't cure it, they stay like that for awhile. If it came like that it's not your fault. Just saying, that's not a healthy fish.
