Thanks for the advice, Lynn!

The thing is, see, I'm not entirely sure if these rice-shaped things are Tapeworm segments or Cricket Egg cases. I'm ruling out Pinworms because, after a bit more research, it's obvious that this is not Pinworms. I've found several pages of people, after feeding large adult, female crickets to their pets finding egg cases in their feces. I can't be sure without a fecal exam, and I rarely find intact feces from either frog unless I see them (for lack of a better term) poop it out. Otherwise, it gets sucked up by the filter or splashed into little pieces by the feet of either Gnag or Bumpy. Both the frogs are acting fine, Gnag (if you call being aggressive and biting the hand that feeds you fine) as plump as ever, and oddly enough, the spots on Gnag's back have disappeared, or at least I can't see them anymore. Even so, I will take him in if I can spot them again or he begins to act oddly.

I don't think it's a coincidence the week I fed them huge, adult crickets (the biggest crickets I've ever seen or fed to Gnag and Bumpy, actually. They were so big I wasn't sure whether they were Acheta Domesticus) is when I've first spotted these odd shapes in their feces, but either way, we can't be sure without a fecal exam. I probably should have done one for the pair of them on an earlier date but there's no point in thinking about that now.

I'm sorry about all these false alarms I've been having with my frogs (this may have been the third of fourth), but I really hope that all this is is a false alarm, and my frogs enjoying some cricket caviar.

I'll try and get a spare bin, I know I have one around somewhere. Either way I could definitely use it. As for their regular enclosure, since it's on the upper stairs, it's probably not going to move.

As for if it does turn out positive, I'll have to follow your instructions. However, it's going to be difficult moving Gnag's tank, so I may have to find a solution that doesn't require moving it. As for Bumpy's current tank, I can move and clean that, although I may be getting bigger tanks for the both of them in a month or so.

But, for now, the best thing to do is monitor Gnag and Bumpy's activity, check for spots on Gnag's back, and wait for an intact feces so we can do a fecal exam and find out whether I've got the worst parasite a frog can have, or if they're just enjoying some cricket caviar.
