Devil's Thumb Coral care?
My devil's thumb looks really dark and not very healthy. when I got him I was not told a whole lot about what type of lights he likes or flow or anything. I have a 55 g tank with 250 watt metal halide with 1 20 watt 50/50 actinic. I have my actinic on for 2 hourts by itself than turn on the halide for 8 hours, then turn off the actinic after 2 hours. Thanks
