Just curious. I have two cleaner shrimp in a Reefer 170. I have a fresh molt about once a week. Seems like a lot to me, but then this is the first time I've had these. They've been in the tank for about 4 months and are significantly larger than when I put them in, everyone seems and looks healthy.
Mine would molt every 2-3 months or so, but they sat in a prime spot to catch food entering the tank...that, and I feed them quite a bit, too
