I would be too quick to blam the emerald either. Inverts are sensitive to poor or changing water parameters. Can you post your SG, NH3, NO2, NO3, Ph and temp?

I know they were killed because I saw the blue legs laying on the sand bed. I guess he doesn't like the taste of those. I'm not going to get rid of him yet.
My parameters are good.
ammonia 0
nitrite 0
ph 8.2-4
sg 1.22
temp 76
nitrate 10
My tank is only 7 weeks old. I filled the tank with tap water to find out that my water was high in nitrate and no telling what else. So I bought a ro/di filter. I did a 75% change after cycle and another 20% change before adding the crew. Still trying to get the nitrates to 0.

You did see an empty shell, right? If not maybe the crab just molted.

Still, you won't be OK until you return the crab I'll bet.

The problem is that I have around 10 empty shells in my tank. Not sure I know what molting is?

Inverts like shrimp and crabs molt. Think of it as snake shedding its skin. It is how they grow. The molts look exactly like the crab and are often mistaken for a dead animal.

This is what I was thinking. Mine took about 3 days to move. I thought mine was dead, but I sawhim moving 3 days after his molt.
