What is this creepy crawly critter? Found
him near a small piece of rock I recently removed from the reef tank for my Algae ID post. Hard to tell from the paper towel, but he had a white sac-like thing on his behind. I had given the rock a good peroxide cleaning and put it on the paper towel on my counter. All the brown algae was gone, there was still some green algae. Then found this little brown thing crawling around a few hours later. I don’t know if he’s from the air or reef tank, but I’ve never seen anything like it.
