Zoo Med UTH for hermit crabs. There are 2 types. One is small and circular. The other is larger and rectangular. These will say on the paper lable over the adhesive on the UTH that they are glass only, but the actual instructions in packaging says that the Zoo Med UTH item# RH-7 and the Hermit Crab UTH are the only 2 safe for plastic.
