it is hard to tell how a fish will turn out from fry. it looks like it is developing pearls. it is starting to show color at a very small size so that is a good sign. just be patient and feed good food. then you will just have to wait and see. fh grow very fast so it won't take a long time. fh eat like pigs and can grow as much as 1 inch a month. the humps (kok) grow at different rates depending on alot of factors, mostly genes. if your fish is male and his dad has a large hump, then there is a much better chance that yours will have a big hump. there are ways to get it to pop that other people know, but i am not into that. i like it to look natural.
