The oldest has been keeping a marine (salt water) fish tank for a while now. One of the residents of that tank is a Skunk Shrimp, Lysmata amboinensis. Apparently the tank agrees with it, because it moults every few weeks. The first time it happened, I thought it had died, but then it occurred to me that it wouldn't have... dissolved from the inside. Sure enough, the shrimp was off doing its thing elsewhere.
The shrimp actively seeks out the fish, trying to clean them. The fish took some time to get accustomed to this, but they all seem to enjoy it now.
