The most indestructible coral is...

Green Star Polyps. I've removed the rock from the display tank and left them in a dark sump for several months, burned them with a butane torch, scrubbed them with a tooth brush, smothered them with epoxy, peeled as much of them as I can off of the rock and still they keep coming back and wont die. I guess my mistake was not doing all of these things at the exact same time. Now what I don't understand is occasionally I encounter someone who cant keep them alive. I can only imagine that they must be accidentally keeping them in a fresh water tank...

Mushrooms, kenya tree, aptasia and anthelia were all MUCH easier to get rid of. Oh well, time to pull out the torch again. In 20 to 30 years when most (all?) of out natural reefs are dead and gone we will still have green star polyps growing along the tropical shorelines.
