I don't quite understand what you are asking...If you are asking is that fish a flowerhorn? Who knows. Yeah its a hybrid, flowerhorns are hybrids. I guess it could be.
Ask yourself what the definition of a flowerhorn is.
To me if it has a big bump on its head, its pretty colorful, and its a hybrid, then yeah its a flowerhorn.
I don't think anyone here can tell you the exact ingredients that will yield the flowerhorn in your avatar or anything like that, its just a gamble with these fish. Its all genetics, I mean 2 fish could produce an offspring that look like a flowerhorn, but is it geneticaly a flowerhorn?
And then if 2 flowerhorns produce offspring and they look nothing like flowerhorns, are they still flowerhorns?
****s confusing, if you like the fish buy it and grow it up. Don't worry if we say it is something or isn't.
