Frontosa, and other naturally occuring humps are alright. However, I think when it's specifically bred for (like Flowerhorns) it gets to be too big and hideous.
Humps are ok in my book to a certain extent. I hate RDs and FH with huge humps it's ugly but I like Rds and FH with little humps. Cons look cool with humps. P-Bass look like little pimples on it's head lol or like a Horn.
