I've got a 20 gallon tank w/ a mesh lid that slides into the top.. Cartman, my WTF just tried to jump out as I was closing it..I squashed him! He is still hopping, and I pulled back just as I realized I got him.. I didn't squish him hard..but I hope he is okay?? what should I look like as danger signs?? His back legs still work, but I just worry, i love him so much and feel so bad!!!
