killer crabs

i have 12 blue legged hermit crabs and 12 astrea snails in my tank. one by one the crabs are starting to attack and eat the snails. is this because they dont have enough food, want the shell, or are just aggressive? i know i will need some bigger shells but i have only had them for a few days and figure they could go a week or two without bigger shells to move into. whats the deal?

LMAO.


But yeah, you've never seen the Discovery Channel specials or anything?

Hermit crabs, if wanting a bigger shell, will rip whatever is in the shell it wants out, and take the shell.

As long as there is a superior empy shell, they have no need to go after a snail.

I have to disagree with that last post....I dumped about 7 empty shells in my tank for that reason, and have had one of my snails killed and had its shell repo'd. A day or two later, i found that same hermit all cozy in its brand new shell, going after another one of my snails....I had to take matters into my own hands (i am down a hermit now )Just last night I found one of my hermits inside one of the empty shells I put in there. Its soo funny to watch because the shell is huge and it was on its side when he got in it and because it was soo tall, he couldn't move b/c his legs wouldn't reach the sand. I had to tip him over a little bit to help him out. Its still funny to watch b/c all you can see is this shell moving, you can't see him b/c the shell covers him. Not a dull moment in this tank!
