These red belly flower horns that are sold in neighborhood pet stores will not grow a hump. these stores buy what the breeder don`t care for. breeders usually keep the best one`s, and those will go for more money. to find a good flower horn, you can`t go commercial, look for them at a mom and pop store. you have a better chance in finding one that will have a hump at two inches already. that is how you know they will have one as adult. once I learn how to use this web site, I will post the two I have so you can see what they going to look like. pretty, but no hump.
