I recently bought a 2nd cleaner shrimp for my tank. He initially seemed fine, but after a few days he became less active and started developing tiny brown spots/lines over his thorax. Over a period of 72 hours these "spots" became more numerous eventually resulting in death. Today (a few days later) I noticed that my other shrimp (who has always been fine)is starting to develop the same brown spots. What is this and is there anything I can do to treat/prevent it? Is there some sort of worm or parasite that specifically affects crustaceans? I can't seem to find any info on this.
