When I first set up Paddy's tank, I had Flukers moss in it, after doing more reading I found out it can be an impaction hazard. So I removed it. A few days later she was eating a cricket, and caught some of the remnants of moss in her mouth, she was having a really hard time with it and I actually ended up pulling it back out of her mouth. I won't go back to flukers, so it'll either be live or leaf litter, just not sure which!
