No worms should be a staple food. They are high in protein and fat and eventually the fish will likely develop intestinal issues.
Live foods like daphnia are excellent; brine shrimp but not in excess due to the exoskeleton; blackworms as treats. If you're in a warmish climate, small ants, mosquito larvae [these are easy to culture in warmer weather], almost any very tiny incsect or larvae.
Frozen daphnia might work; unfortunately I cannot buy this in Canada [don't ask why, it is silly]. But I can't any longer; I used to, and my small fish loved it.
I've never had much success with frozen brine shrimp, it thaws to become all mush or something, and the fish were never partial to it.
