Dwarf Zebra Hermit Crabs

[BuschWacker]

Personally I would not buy another one. He's good with corals, hangs out in my birdsnest, but doesn't harm it in any way. I also had a few scarlet hermits, and they were model citizens. Never fought, or bothered anything else. I enjoy the crabs in larger tanks, but don't think I will put them in nanos anymore. I never actually see it doing anything constructive. At least my snails are always cleaning. The crabs only ever sit and stare at you from across the room.
