Bought "Assorted corals" from Petco, but no one knows what it is.

Flowerput coral, and a dying one a that. considered extremely difficult to keep, most seem to do well fora few months then wither away.

Thanks! That is it! I'll keep you posted if I'm able to bring it back to life.

The flower pot is doing very well, it's increased in size by 50% and is vivid bright green at the ends of the "petals."

If the tips have gotten iridescent then it is either stinging or getting ready to sting neighbors. You may want to move any corals that it can reach to insure it does not sting and start a chenical war in your tank.

Thanks. It's tentacles move all over the place, but it's only touching a piece of live rock. As it continues to grow, I'll keep that in mind to make sure that it is not able to touch other corals.

Definitely Goniopora sp. They an prove difficult to keep alive for extended periods, here is a good article on their care... http://reefkeeping.com/issues/2005-10/nftt/index.php
