No clue. 90% of my rock was dry. I purchased stuff from roughly 4 members on here only. Must've come in on some corals or corals attached to rocks.Where did it come from?
My tank lights were off but the room was pretty bright. I saw the sickle shaped end sitting on the sand. Thought it was debris or possibly some weird worm. When I touch it, it shot under the sand. Curiosity lol I start digging at the sand and it's no where to be found. So I go back to cleaning some bubble algae off a torch base and now it's whole body is exposed and crawling along the sand. To be honest there was no way I was touching that thing on purpose haha. The movements looked like some brain eating amoeba from a sci-fi movie haha.Hope you were wearing gloves, lol! Did you find it in the sand or under a rock or what?
