wow thats a nice reef tank! i love that u have had it up for that many years!! love the anemone and clowns!! The potters angel is also a very cool fish!
The slimer came from a fragging demo. Instead of a 2" frag for $5 I got a 12" heavily branched "frag" for the same amount. So with all the handling it had that day...it slimed a ton in the tank. The slimer didn't touch the bubble but the slime from it traveled over via powerhead and a bit burned it there on the top right in the photo. It has since healed.
I love your bubble, I'm not exactly sure which one I have. I saw the frag it was from...it was one skeleton but had 3 polyps. They weren't tall like the branching ones i see photos of but rather 3 polyps one one base. Is you'rs one giant polyp or does it have multiples?
