Night Time Surprise! What is it?

[Betta132]

They aren't quite that good. Pistol shrimp use a large, modified claw to send out a vaguely bullet-shaped shockwave of sorts. It's effective up to maybe half an inch away. Won't kill things, but it scares them and stings pretty badly. Soft-bodied things like worms can be stunned, and the pistol then grabs them and drags them down into the tunnel to pull them apart.

Where'd you get that picture? It amuses me.

I just searched pistol shrimp on bing I believe.

Don't worry about the cyano bacteria on your rock. You can brush that off before adding to your new tank. Basically the conditions in your buckets are good for that to grow now (probably not great amounts of flow delivering oxygen everywhere plus some of the living stuff in the rocks dying - it'll grow back in the tank).

Don't freak about the bristle worms. They will in any case mostly hide under your rocks and just grab detritus (good). Boxer shrimp will also eat them, but really don't worry.

Do try to observe your live rock for aiptasia (glass tube anemones) and do kill those with Joe's juice should you see any. They can be a PIA for the beginner to get rid of later. Strongly recommend checking this rock for that.

Basically worry less about keeping things sterile and more about the conditions in your new tank, doing a good cycle, adding livestock very slowly and not over feeding.
