I have had maybe 3 or 4 fish that wouldn't eat pellets no matter what, but I didn't let the fish die, I just gave in and decided I'll feed them frozen for the rest of the fish's life
Not all species of fish will eat pellets in captivity. Not all freshwater species, and not all marine species.
I too have found datnoids are really stubborn when it comes to eating pellets, I've managed to get them to eat frozen though. I usually take a silverside and jam pellets into it and they don't notice the pellets most of the time.Well spoken rd. IME datnioids are stubborn as hell on pellets. Most cichlids ive kept are easy and same goes with rays. Ive got two bichirs that refuses pellets 9 out of 10 feedings. And they can refuse food for weeks then suddenly eats again.
