Pinkish, Orange Little Wormlike Things in Tank


New Member
For the past few weeks, when the lights turn on the tank at night, I’ve seen 3-4 of these pinkish, orange wormlike things with antenna attached to the glass. They’re anywhere from 1/4-1/2 inch long. It’s almost impossible to get a good picture. I’m starting to get concerned. No new fish, crabs, snails, or corals in at least six months. What are they??
