Your tank is still cycling, so you really should let it mature some more before adding anything else. Have you measured nitrite? I am sure it is high also. You may want to consider finding someone to hold the anemone for a month or two until your tank finishes cycling.well i checked my water and as i say it read0.25 in the ammonia
As for it's moving around, anemones do that. They are mobile creatures, usually when they find a good spot they will hang out there, but that still doesn't mean the placement is permanent. Every now and again they decide to go on walk-about, :banghead: .
