I changed water and vacuumed my sand. I started in one corner. When I got done with the water change this critter had crawled up the glass in that corner of my tank. I think I disturbed it. It is about 1/2 inch or so long with long antenna, little black eyes, greenish body (outside the tank light - appears all white in the tank with Kessil a360x), purplish partial shell. moves pretty good. put it in a cup and it tried to crawl out. have it in a specimen jar now with a lid. I dip everything before it goes in my tank. not sure where it came from. No new frags for over 2 months. Is this critter harmful to corals?
