I have a few questions. I have had a 55 saltwater aquarium set up since last august. I have about 40 to 50lbs of live rock, a clam, a flowerpot, and a 4 stripe damsel and a yellowtail damsel, and 2 bubble tip rose anemones and a pink anemone. Since i have put these anemones in my tank they have never acted right. I have a t5ho lighting set up. During the day when my lights are on the anemones are very small, they shrink against the rock. At night when the lights are off they reach for the lights which indicates to me that they are still alive. They are also bleached. They do not feed often because they are often shrunk. I need help trying to figure out what is wrong in my tank. My water has been tested often and nothing has ever been wrong with my water. Does anyone have any ideas for me?
