Be careful with snails and slugs, if they breed in your enclosure they can seriously ravage your plants. If your like me and love your plants this can be a serious problem. I’m speaking from experience, I released about half a dozen slugs from my yard into a bioactive frog habitat. They are active at night and after a day or two they had done some real damage to my plants. So I spent A couple nights hunting the little vermin down.
Easy way to avoid this is to feed them one at a time and remove if it isn’t eaten.
