I have a Red & Black Sea Star (Formia milleporella) from LiveAquaria. It's been in my tank for about 2 days. In the notes about this critter, it was stated quite clearly to avoid exposing it to the air, or risk infection or necrosis of an arm.
However, since I put it in the tank, it has climbed up the rocks, up the back glass, and now sits at the water line, waving one or two arms in the air 8O
Should I worry?
Water Params are 79deg F
Ammonia, Nitrites and Nitrates are zero
I have Power compact daylights and actinics, 4 (2 and 2) at 96watts each
