Pics of your Dumerils?

My other concern with aspen or cypress is them eating some when we feed them. Is that an issue

Keep the dum healthy in correct temps, and it is not a problem. They are able to digest bones and teeth.

When they get substrate stuck in their mouth, they do a good job of getting it out too.

If you're worried, you can always place a plastic lid into the enclosure and feed on top of that.
