hows it goin lil mama?
right now, i have to be completely honest with you, he has not much for kok, his body color will most likely get more intense so i wont comment on it, but i do really like the golden body color behind the purple, doesnt really have pearls, but Red Dragons (i think this is what yours is) dont generally have pearls, especially the old school RD's, which are one of my favorites, i hate doing this cuz i dont wanna hurt peoples feelings, so please understand that im doing this for you to learn, not to be an @$$hole

, and i expect people to do the same for my own fish

i hope you havent taken offense to anything i have said, and if u have i apologize sincerely.
but everything i just said may be fixable! if he was just put in the tank, he does appear that his kok may pop out a bit, color will intensify as he grows, just dunno how much, you say he was brighter red, so that will come back, and in your care probably more then at the LFS. update us every week so we can see his/her progress, it is a flowerhorn after all, anything can happen, and at 5" it is still very young, so be patient.
