I've read that upside down catfish will swim to the surface for feeding, but mine seem to stay on the bottom during suppertime. I usually feed flakes to all the fish, and once or twice a week they all get freeze-dried bloodworms or frozen brine shrimp. The other fish seem to eat all the food at the surface and leave none for the catfish.
Do I need to get pellets that sink to the bottom to make sure my cats get some food?
