The TRUST said:Well it really depends. My friends used to breed discus a lot before and he had many fry that were unsalable. The ones that need to be culled. He never had the heart to do it. If he gave them to me, I'd certainly be more than happy to use them as feeders. Heck I'll use any fish as feeders as long as they are no poisonous and are free. But I agree that paying for an expensive fish and using it as a feeder is dumb.
I didn't think about culling, that would make sense.
