HCA: Hermit Crab Association

I wish I could find E's in the NYC area. Everywhere I've gone have been PPs. I'd really like an E especially since I recently upgraded to an 55g tank.

I'm I also bought an UTH, but it says it's for deserts. I havent installed it yet, but would it be okay to use for my 10 gal tank?
