Can anyone please identify these critters I was looking in to my tank at night with a flashlight and there was approximately 15-20 of these critters swimming around like mad and attacking the sand and live rock. I have a 110 gal. Tank with 120 lbs of live rock (Tonga and Marshal Island). Tank is been running since mid November. All parameters OK and have one small lionfish. They don’t bother the fish but they are swimming around and almost attacking the sand. What are they and do I need to get rid off them? They are attracted to the flashlights beam and I don’t see them during the day. Please help!
Thanks
