Mystery Murder or Death by Unknown Cause

[AKL1950]

Well, the shrimp in the above post is no longer with us. Found it this afternoon with its head missing. Pretty sure it’s the same one, because it has a big green abdomen. Now I’m unsure if it’s a chemical problem or a predator. I still suspect chemical, because the first one I found was completely intact. The other two probably lost their heads after death. I suspect it’s only time until I found #4. Very sad. ICP will be sent Friday. I ordered the ATI so I can check the the RO-Di water. I made new salt water three days ago and started using it Sunday. I’m shutting off the auto water change till I get the test results. Can’t help these guys, but hopefully can find an answer for this. Tested Copper and it’s fine. 0.09.
