I’ve never had one grow such a large nuchal hump before.... and I’d like to believe that it has everything to do with genetics and nothing to do with me. Haha
he has no female to impress and only lives with a large reed fish and a medium polypterus
I know they say genetics are a huge part but it seems that other variables are involved...
Hormones from fish ready to breed area factor for sure. My fish that were ready to breed both got nice humps, this includes the female. Not as large as the male but it did come in. I swear I saw a little growth in the other male midas at the time too.
I know the food thing is debatable but it does seem that the high protein flowerhorn foods do seem to promote hump growth. Though the high protein diet makes for unhealthy fish long term.
This made me think about the Flowerhorn “grooming” where they put a mirror up to the tank to encourage hump growth.
