Help! Clown Knife not eating!!

[schmitzie]

Help! My 13" Clown Knife is not eating the pellets he has been raised on. What should I do? Do I buy another brand of food? I'm at a loss here. He is housed with an Oscar, Parrot, Red Devil, Eclipse Catfish, and a Turquoise Severum.

If it were me, I'd read this, then post some of the requested information. Otherwise, we'll all have to guess, which isn't often productive.
