Mine does it every few weeks as well. Always have to pull out shrimp skin off my Vortechs, haha. Mine are also carrying eggs too, which I've never seen.
The first few times it happened, my wife called me at work to inform me that my pistol had died. She doesn't bother anymore. I've always wanted to capture it on video.
I pull mine out only cause it usually sticks to my powerheads, plus, I don't want something rotting in my tank. It can't really hurt to pull it out. I can't see it being beneficial for anything.
yes we have all heard that. lol
shrimp molt every time they grow. if tis every week its just fine. if you had adults that dont molt 1 times a month well then i would say your iodine levels might be abit low
They do about once a month I think. As others have said, they seem to do it more often when you do water changes. I leave my skins in there, I heard a while back that they are full of nutrients that help others in the tank.
