Hey all, was wondering, My cleaner shrimp molted,should I leave the molted carapace in the tank for tank mates to enjoy or are we talking decay and raised nitrates here?

I usually just left them in the tank.

That should be just fine. Since shells are made primarily out of chitin and a tiny amount of calcium carbonate (and even smaller amounts of other things), they are relatively 'safe.' Because of this, it takes them a long time to break down, so it is not going to be a problem for the tank.

I never take mine out. The crabs usually eat it.
