baby catfish can eat small frogs, but it depends on the size of the frog and the catfish, as catfish are opportunistic predators that eat anything small enough to fit in their mouths, including insects, tadpoles, and small vertebrates like frogs, though some owners report peaceful cohabitation with dwarf frogs. Larger catfish readily consume frogs, but even small ones might nibble on tiny froglets or tadpoles, so it's generally best to avoid housing them together if you don't want predation. #fy
