Hello guys I had a nem of mine get into one of my power heads around 3 weeks ago, he still is alive but his behavior is weird. He doesn’t come on top of my rocks he was hiding under a rock in a cave. Took that rock out he footed in the same place but moved the same night to the other side of the tank under a different rock. Also when I took the rock out he wasn’t attached to anything. His foot didn’t feel really sticky I never remember it being sticky even b4 the accident. Also I caught him with his mouth open and I’ve heard on other threads that could be a bad thing. Why. And I wonder if it could be lighting. Thank y’all it really helps. Also my tank is 3 months old and I’ve had him for a month maybe more. Newbie mistake LFS didn’t mention nems needed established tanks didn’t look it up. I believe the nem is a magnificent anemone. Pictures are b4 getting In the power head. Don’t have any of him now.
