Yes if your cham will eat them. Mine never wanted anything to do with them. Everything in moderation and they are crunchy😩
Or you could start your own little colony?
I also have been doing this ever since I started my colonies. Works great with no wasted food scraps to mold or pick out.
You can make up a big batch and put them in the freezer so you don't have to worry about gutload. Yours is a little different color tho, usually it's green.
