Fast they are! It's always a challenge to catch these on camera. These are small isopods, and appear to be highly tolerant of humidity and poor ventilation. These might be good for a moister bioactive setup, although we haven't tried them with dart frogs quite yet. Like most detritivores, they will eat just about anything, and seen to like rotting wood. Ours love to run inside the little holes; they're very hard to catch. Truly a fascinating species, and unlike A. nasatum, A. vulgare, and P. scaber, Atlantoscia floridiana is a North American native--not a European transplant.
