Hey i have 6 mono Pb's in my 55 grow out and all of them seem to be ok but one. he ignored food for the first time ever and looks a little skinny, what he will do is take a bloodworm into his mouth then spit it out. He did the same thing with the Pellets i tried giving him. Its almost as if hes just trying the food and spitting them out. The Water perimeters are fine nothing bad is happening to the other fish only this little guy. Food is Frozen Hikari blood worms i thaw them out and put one pact in slowly at a time till i see them all eat in the tank. If anyone knows what could be the case plz help thank you. Right now i believe it could be internal parasites but he swims fine and is not getting picked on. I cant seem to figure this one out, im probably going to throw in some live guppies tomorrow to see if he will except that. cant get pics my camera is broken
