If you want to know how to tell if your crayfish is about to molt, let me tell you a short story and give you the tell-tale signs that your little buddy is about to shed his exoskeleton.
About four weeks back I bought my electric blue crayfish a new hideout.—Mainly for the purpose of giving him a better place to hide out.—Especially during molting.
Well ironically, as it turns out, my crayfish literally molted two weeks after buying the hideout.—But here’s what happened leading up to when he actually molted.
How to Tell if Your Crayfish is About to Molt
The first thing I noticed about my electric blue crayfish that made me think something was going on was when he seemed to hide all day long under the hideout in my fish tank. He’d come out periodically to snag a sinking wafer, but that was pretty much it. Other than that, he was nowhere to be seen. He had become totally lazy.
My crayfish have for the most part always been pretty lively unless I overfeed them. Then they just go under a hideout or burrow somewhere.
After a couple of days of my crayfish doing nothing except burrowing in the same exact spot under the hideout, I became a bit concerned. I actually checked on him a couple of times to make sure he wasn’t dead. Luckily I saw movement.
On the very day that he molted, he actually came out briefly, but quickly went back into hiding. At this point I was watching closely because I had just dropped him a sinking wafer, but he was not going after it like he normally did when I fed him.
After watching for a little while, I stepped out of the room for just a second.—Maybe five minutes tops. When I came back, BAM… I saw the blue exoskeleton lying outside of the hideout. He had molted.
