I just bought an LTA and he was doing fine when I first put him in the tank. Then I bought a bio cube circulating pump to have water flow and he got stuck to the fan I turned off the fan and immediately took him some of his tentacles were withered. Then he seemed fine again, the next morning I put some sea salt for electrolytes some landed on him and know he is all swollen up no tentacles showing. It's my third anemone I've traded out do to other problems and my water is fine.... Please help I'm mostly concerned about the swelling!!
