HCA: Hermit Crab Association

I agree with Got butterflies!

We have UTHs on the back and one side of all our tanks. It gets really cold during the winter months and the side heater really helps.

I'd say no. Too many unknown ingredients, plus added coloring. I know I wouldn't give that to any of my crabs.

Eggshells and cuttlebone

Nice upgrade! Watch the netting on the back. Crabbies try to go thru the holes and could get stuck or tangled. Do you have any playsand mixed into your substrate?

Yes, my crabbies eat their exo after molting too.

I would say yes, all the sand needs replaced. It's bacteria. It grows and spreads. We scrubbed the tanks clean and scrubbed everything in them. Boiled, threw away, whatever we had to do. We treated it like an infectious disease. We didn't want to take any chances at all. Especially after losing 2 cr...

15 cm doesn't sound deep enough. That's just under 6 inches. How many crabs and what sizes? I'd go with a minimum of 8 inches of substrate. Check out the care pages on here. There are links. We use UTHs from the Bean Farm and Reptile Basics on the back of our tanks, above the substrate
