Hi,
Noticed over the last few days that a thick tentacle type thing has appeared on one of the rocks at the back of my tank.
Every now and then it comes out, has a feel around (feathery looking bits come out of the end) and then disappears back into the rock.
Any ideas what this is and if it is an issue?
I've also attached a picture of a couple of thin ones that have appeared elsewhere in the tank.
