Hello, I have this rather large GBTA that keeps growing and is now threating some of my SPS and softies. I have 2 so my maroon clown will just have to settle for 1. Ruler is on the glass you can get an idea of it's size. It's been attached to a nice shelf piece of LR with red with grew spot shrooms for over a year. Since it's on this rock asking $30 or trade for just about anything. PM for more info or pics please. Sorry just quickies with my phone.
