Is this fish stunted?

[qiyanfeng]

I got it about 2 months ago at 2.5". Now it's about 3". Smaller than the others. The first couple of weeks, it eats well. But recently, I feel it losed appetite.

thanks a lot for the answers. It is about 4-5 months old I believe. I just started to feed it with beefheart. 50% water change every other day.

I believe that at that age it should be around the size of a tennis ball - don't know if that is any help. The ratio of the eye size to body is a good indicator if its stunted and also whilst its young its possible to get it back on track. Looks okay to me but I have not been keeping discus for that long.

Hope that is of some help

I would more concerned it being off it's feed. Any white poop? (thinking worms) or is it low man in the pecking order? You might consider daily WC especially since these are juvies. Also Francis's suggestion is a great one. ;)

I would say not to me looks in good proportion for its age. Try giving it some bloodworm.

Bloodworm is more of a filler than a growout food. Francis's suggestion is a great one. Good luck and keep us posted.
