That’s not a good food use more like tilapia and shrimp and use melafix and stres coat
Maybe cut the tilapia and shrimp into worm shape but worms aren’t a good food source
You can feed them it but it doesn’t provide much nutrients
Have you tried live?
I'd be curious as to the source of this opinion regarding earthworms. Earthworms are whole organisms, containing all internal organs and complete with alimentary canals full of partially digested food. Strips of Tilapia are just fish meat, not even close to a complete diet. I'm not sure about shrimp; whole shrimp would be much better than just the tails which many people buy to use as food. Apparently at least some shrimp pose a thiaminase risk as well.
I wouldn't suggest that any of these three items (or any other natural foods) would be ideal if fed exclusively, but if I had to pick only one I think that earthworms are probably by far the best choice. I've used them a lot for the last 50 years or so and haven't encountered any problems related to feeding them.
They are also one of the most irresistible foods to predators and are often the best way to get a reluctant predator to start eating in captivity.
