I lost about 4 cleaners, 3 blood reds, and maybe 3 peppermints. My pistol is fine and got one of each of the other 3 types left. I found two of them, just torsos. The others, I haven't seen. Got a 75g fish and reef setup. Nitrate, Nitrite, and Ammonia are in great shape. PH is between 8.2 and 8.4. Could Phosphates be a culprit?

There are electric blue and red hermits that have lived with the shrimp for 7 months w/no problems. I've got the peaceful fish, yellow tang, 2 percs, foxface rabbit, b/g chromis, neon goby, & firefish. Got 2 mythrax crabs too.

The only thing I can think that might have happened was that I washed/soaked a piece of dead white coral in 4:1 bleach:water solution. Rinsed it 5 times and soaked it in fresh water. 3 days later, I returned it to the main tank.

Then.... my shrimp started dying or disappearing. Any ideas??
 
No sudden changes - unless that danged Clorox coral did something I didn't notice. Didn't do any water tests right after I put it in.
