Hey guys, Well I know these guys are hard to care for, but it was given to me, and I know the local pet store will kill it before someone buys it so I thought I would give it a try. Ive got the guy about 6 inches for the top, and Ive noticed it want fully extened. Ive got 80 watts of PC power over a 15 gallon tank. I read that they love light, so I thought this would be a great place for it. When the actinic lights come on, and the daylights go off the poylps come out. I dont want to stress the guy any more than it is, but I mite put in near the bottom and see what happens. The green goniopora is 3 inches around, so its not a baby. Any other info on this guys would be great, they are hard to research. Michael oh yea, the green goniopora was under MH lighting before I got it, but I dont know what it looked like, it came from out of town.
