I had it a little over a year, but that picture I linked to was just before the clown decided it was going to try and host in it. It would dive bomb it over and over again. It probably would of been fine, but the clown I think was a little to aggressive. Of course I may of contributed to it also. I was trying to move it around here and there to get the clown to ignore it. But nothing worked. So between me trying to protect it and the clown trying to host, it was probably a combination of things that caused it's demise. It stinks but sometime you never know how things are going to react or what a fish might do.
IE: I have a multi-barred angel that took a liking to the polyp's on a Pocillopora . Nipped it clean before I could figure out what was going on. To cool of a fish to remove so I live with. No more Pocillopora for me.
