Earlier today I saw a thin pancake like creature flap across my tank and into the back of my rock work so tonight I decided to do some hunting. This was one of the creatures I caught and I’m pretty sure it’s a bad one. There were also several other smaller isopods that were shaped like pill bugs but with large black eyes, but they were really quick and I didn’t have any luck catching them. Both kinds seem to favor the sand. All live rock and sand is from Tampa bay if that helps with ID. Also any tips on catching the remaining bugs would be appreciated, since I’m pretty sure these aren’t good guys.
