I lost an emerald crab tonight but I think my coral banded shrimp and him got into a fight because the coral lost an arm also. Is this normal for them to fight or could it be that my Nitrates are 40ppm everything else is normal..Help <img src="graemlins//confused.gif" border="0" alt="[confused]" />

Supposedly CBS or Boxing Shrimp are nasty buggers to other shrimp/crustaceans. I had a pair for a good while, but whether or not the CBS sparred with your crab, I honestly don't know.

My first guess would be that they fought and the emerald lost. I doubt that the trates had a role in your current loss. Not knowing what else is in the tank, I would say that you definatly need to get the trates down before you do loose something due to the elevated level. How much do you feed? You may try cutting back on the food and do a partial water change to get the trates down.
