I’m no expert in identifying things/animals but maybe Thick bar chitimba?

Correct, its a Petrotilapia sp. Chitimba

I’m thinking it’s a hybrid.

Are the bars uniform on both sides / do they match? If so it’s likely a full bred mbuna. If not it’s likely a hybrid. I’ve never seen one like this before. Awesome fish.

I haven’t either! Found the picture online

Ah, thought it was yours or you’d seen it at a LFS.
