View Full Version : What to do with a molted shell?

Before I have heard they get protein from it and to leave it in. I have 4 Crayfish though. One just molted so what do I do with his shell?

I personally don't like the look of them hanging about.
Any nutrients/minerals (I would rather think they got calcium, not protein) they get from the shell would be negligible. Far better to use water changes to replenish minerals.
I don't think it matters one way or the other tho. No harm to remove, no harm in leaving.

leave it, most crawdads and crabs eat their shell to get calcium to build up their new shell.

I always leave them in and they disappear after a day or two. I figure its the natural way of things, so I let them eat it. The calcium boost and such is just a bonus.
