I found this thing on the sand this morning, alive. It's about the size of a nickel. FWIW, I've lost almost all my snails, crabs, and four serpent stars in the last 48 hours, and am trying to figure out what's going on. Fish are fine.

What is this thing? Almost looks like a little tiny shrimp.

I thought pistol shrimp were harmless, he may dig your sand up a little, but that's about the worst of it .. ?

Pretty sure pistol shrimp are harmless and it does look like one. Even if it was predatory, it couldn't have killed all those snails/crabs/stars in two days all by itself I don't think.

No, there's no way this thing killed anything. In fact, it was barely alive itself. Something else has gone wrong, and probably the only reason I even was able to spot and catch him was because he was so groggy.

Make sure you don't have anything with brass or copper in your tank. It will kill inverts fast.

Tested for copper (Salifert) and it didn't detect anything.

Inverts react first to high levels of NO3. If they are all dying do a trate test and see if you are climbing up around 50 ppm or more. Then do a large water change, wait two days and do another and try to dilute the trate. Longterm need to find out source and a solution.

Then do a large water change, wait two days and do another and try to dilute the trate. Longterm need to find out source and a solution. Nitrates are at 10. I had already been doing water changes every other day (around 15 gallons - 100 gallon tank) for the last couple of weeks trying to deal with what I thought was cyano, but now seems more likely to be dinoflagellates. That (the dinos) might explain the dead snails, but to have literally every other invert die within 48 hours suggests to me something more than dinos. I'm wondering if during the course of a water change I inadvertently introduced something toxic, though I have no idea what it could be. I was also trying to increase the PH to help deal with the dinos, but it had only gone up to 8.25, from about 8.15 (pinpoint meter).

Most of the inverts have been in my tank for well over two years, and many were hitchikers on my original TBS rock. To have them all expire at once kinda freaks me out.

10 is not high enough to kill inverts. How about further back the cycle, like ammonia or trite?

if its a pistol shrimp you may hear a clicking noise at night.
