Thank you for your help. I have been feeding pellet food for a long time and they were eating it well, until recently. They used to go after it like crazy as soon as it was in the tank, but now they wait a long time, so I decided to get some frozen food. I wasn't going to use it as their staple diet though.
So I guess I just cut up the earthworm and put it in their tank?
Thanks again,
Trisha.
