THIS....THING is the WORST possible place for a hermit crab to live. here are some bad points :1. it's SUPER FLIMSY2. you have to PAY EXTRA to have hermit crabs SHIPPED to your house(i don't need to waste my time telling you all the bad points about THAT!)3. it's awful! it can't retain humidity (hermit crabs need humidity to BREATHE!) hermit crabs need a LOT more than this dreadful death trap can even BEGIN to offer! DO NOT BUY THIS!!!!!!!thank you :)
