Well some sort of Flowerhorn was my first impression, but tbh not really an ideal specimen (by regular FH standards that is, which of course doesn't mean that it won't be a cool looking fish, in fact the opposite could be the case).
Also if you're looking for a FH with a bigger hump, that probably ain't going to happen with this fish (not sure, it might be a female or genetically it just didn't happen). But such is a personal thing, I prefer FH with smaller heads.
