@potatoyay I’ve seen it repeated a lot that they’re too high in fat which causes health issues, the fat content goes up with the size of the worm so I harvest mine when they’re small to reduce the risk.
I’ve also read that fat is good for them so not sure what to believe, mine were getting the choice between mealworms calci worms and crickets but they didn’t like the crickets so I stopped getting them, they don’t like calci worms much either so I probably won’t get more of them either when they run out.
Apparently it’s illegal to give them mealworms or calci worms here in the uk unless you raise them yourself and I don’t like the idea of keeping calci worms so that’s also a factor to consider, I’ve been raising Dubia roaches instead which have a good nutritional profile and they like eating them.
Is that an English/dotted white in your pic? I just ordered some eggs because they were advertised as being calm and friendly towards each other, do you find that with yours?
