Molting hermit crab?

[MikeP]

Yes they molt, and as they molt they grow which means they need bigger homes. If there is not a bigger shell in there they will kill a snail that has a bigger one. I'm not sure what happens when they have no shell to move into at all (maybe someone else can answer that).

PS this is the type of post that should go in the reef section.

Thanks for the info.

I'll get some bigger shells.
