I have a 20 gal. zoa dominated tank (also with several rics/shrooms, a toadstool, torch and hammer). I added a bubble tip anemone a few mths ago for my percs so I've been thinking of upgrading to a 4x24w T5 fixture for the anemone. I currently have the Current Orbit 2x65w PC fixture that has been running on the tank for about 1 yr. Question is, would upgrading to the 4x24w T5 shock, burn or bleach the zoas? Would I have to acclimate them to the lighting change? If so, what would be the best way? Thanks.
