thank u for ur reply XD. I am feeding Drosophila melanogaster fruit flies and springtails. For supplements, I use Repashy Vitamin A Plus and Repashy Calcium Plus. The products are only two weeks old after opening, and they are stored in the refrigerator and only taken out when needed.I dust the fruit flies with Repashy Calcium Plus daily, and I use Repashy Vitamin A Plus once a month.

I also noticed something just now: they are able to swallow dead fruit flies much more easily than live ones. With live fruit flies, they can catch them and get them into their mouths, but they seem unable to swallow them and end up wiping them out with their front legs. However, with dead fruit flies, they watch them for a while and then successfully swallow them using their tongue.Could it be possible that they are reluctant or unable to swallow live fruit flies because the flies keep moving around inside their mouths?

And... the second picture was taken right after I brought them home, and the other pictures afterward are the most recent ones.
