I think my pink tip anemone is a total hippy. I have had it for a few months. First it settles on a nice rocky place for about a month. One day it climbed up in this sargasm patch, and just kinda moves around every now and then. It looks healthy and I have been feeding it(krill). It seems to like the light when its on and get as high in the tank as it can. At night it moves down and kinda burries itself in the seaweed. I am using a 250w MH for 8 hours on a 37 gallon tank. Just wondering if these things always move around, or settle for good?? Should I be concerned?
