I put it in my 90, in the corner and it looked great for about 2 weeks, then it just melted away. pretty gross, slimey and the tank crashed shortly after that. I had also came into a bunch of Corals from a friends tank. He shut his down and gave me everything and they all died with the crash, Shortly after that the friend wanted some cash for everything. It wasn't a good time.I did finally settle with him. Hey he was and still is a good friend, just a misunderstanding. Another lesson learned.
