This is my third cleaner shrimp. It was doing well, until yesterday when some light algae appeared on its antennae. The next morning, I find it dead next to a half-molted shell. At this point I’m not upset, just really angry. All I’ve read is that cleaner shrimp are easy to keep alive, but every time I drop 40 bucks down the drain, it always goes wrong. In an otherwise mature reef, I’d expect these things to not happen as often, yet here I am yet again. Where did I go wrong?!
