I have had my tank set up for 6 months. Everything was going really well. I bought a draft lion and put him in the main tank after QT with other tank mates I already had. Within about three weeks my tang, damsel, clowns all had what I thought was ich. I put them in a qt tank and treated. Not being sure it was ich or something else, I took the whole tank down. Cleaned the LR, sand and tank. I recyled the tank. After it recycled I put the remaining fish that had not died in the main tank. That was the lion, butterfly and one damsel. I bought new fish, QT them and put them in main tank. Now about three weeks into starting over again all fish are dead again except the lion All levels in tank remain normal. temp good. Snails and crabs fine also brittle star and leather coral. I don't know what is causing this. I spoke to lfs person tonight and she said her guess would be that the lion fish is attacking the others at night. She said the fish are dieing from the stress or being stung by the lion. The lion seems very peaceful during the day. I have never seen him attack anything. How possible are her thoughts? My problems did start when I got him.
