I have a 55 gallon tank with one clown, and angel and one damsel. However lately, my anemone seems to be shrinking. I just changed the light bulb (135 wat compact light). The water condition are fine. I was wondering what else could be causing the anemone to shrink. I feed it about once every two week either phyoplakton or squid. The anemone has been in the tank since thanksgiving and the tank has been set-up for about two years.
