i just got some more lr for my nano tank along with an anemone + clown fish, and when the light has been off for a while, i noticed this weirdo slime string coming off the rock with 2 appendages off the tip of it. I shined a light on it and it was apparently coming from the back of the rock and was roughly 4-5 inches long, and it retracted to the back of the rock. It looked greenish blueish and kinda softish. What the HECK was that?
All answers greatly appreciated.
