It was straight from the ocean (and a box) to my tank. I've only seen one questionable critter (and searched the tank at night with a red flashlight). But the Banggai was actually really small and I have searched all over for it (even moved the rocks). I have some BIG scarlet-legged hermits in the tank, and I think they made a quick meal of it. They also killed all of the brittle stars. I have seen a few crab corpses, so maybe their Battle Royale is part of the pollution problem.The KP Aquatics rocks you added to the tank....was this coming from your main tank or did you recently get this order? I ordered from KP Aquatics back in Jan and had to QT the rocks. I removed some bad critters and still have one left in my tank which I think is a Mantis. I have set traps and removed rocks trying to get it out. I had two fish disappear one after the other. I just added two more fishes yesterday. Let's see if they survive. One of your fish must have died and is polluting your water.
The water still looks gross, but the glass isn't coated this morning. I'm hopeful the filters, skimmer, and UV sterilizer will at least keep it steady until I can do a WC tomorrow.
