Hey guys new to the forum. I have a 65 gallon with a sump/refugium and skimmer 75 lbs LR that was dry when started and 100lbs live sand it's around 3 months old. I was impatient in the beginning had a couple set backs but things are getting better all fish are in a QT tank because a yellow tang I bought gave them ich. However the display is looking great thanks to my new clean up crew.
One of my live rocks are getting these coral looking things with tentacles growing out of tubes. Any ideas???
