I've actually had flower horns in the back of my mind for a while now, I've never kept one but always been curious about them. Let me just say, i know a lot of people love the massive nuchal hump (or "kok" as I've heard it called)...but i really don't like it when the males get such large humps thats its starts to look really unnatural and strange looking. But apparently I've heard that "low-grade" flowerhorns, even males, won't get the massive koks that get so big they make swimming difficult. Could a "low grade" flowerhorn be the way to go? I'm not really sure what makes a flowerhorn a "low grade" or "high grade" but there is a local PetsMart that sells flowerhorns and i was told that any FH i could buy at petsmart would be a low grade. Is this true?
