Mann I had a gsp before same kind, not to concern about it, if I see it going crazy I will just take care of it, my gf love it that's why it's in there, anyways the frogspawn is keeping it on check, am kinda concern now that I think I have a mantis shrimp on there, haven't seen it but the clicking noise is driving me crazy, plus no shrimp that I put in there survive, and seen some hermit crabs outside the shell dead
