Most likely a hybrid of a flowerhorn and trimac..
If you have to question the fish, don't know its history or its source, you can't say that it's a Trimac. By the way it looks, it is some type of Flowerhorn. That's the problem with so many people using Trimacs to make different FHs. It can get confusing when a person is trying to ID their fish. Going through a reputable vendor or hobbyist is the best way to get a Trimac.
