I bought a 2.5" carpintis from fishfarm two days ago. He seems health; he's active and doesn't hide or anything weird. However, he won't eat. I drop floating pellets down to him, and he just looks at them. Then the silver dollars come and eat them from the bottom. I bought a small pike cichlid at the same time, and it eats fine. The only thing I've seen the carpintis eat is a few discus pellets I got as a free sample (they are small and the sink, so I figure they are about the right size) and 2 or 3 frozen brine shrimp. This is weird. Any ideas?
