What the heck is this thing? :help: I bought it as an unknown polyp, for about ten bucks, and it has gotten huge, compared to it's original size, and just keeps growing. I glued it to a piece of live rock, and it has, at least, quintupled in size. I thought it might be an anemone, at first, but it has never wandered, and the new polyps seem to be attached to the first, still. I would love to buy more of these things, since I started a 120 gallon tank, and it would be hard to frag this sucker. I feed it mysis, dried plankton, pieces of silverside, and any other meaty foods I have on hand, and it gobbles it all up, and then, after a month or two, it starts a new fold/polyp. I feed it, at least, once a week, and it shrinks, a little, the next day, but swells up further the day after that. I have it high up in the tank, in a 6 bulb T5HO, 75 gallon tank. It seems to love it there. Any clue? Thanks, a million!
