we had one of these guys at the lsf i used to work for until a tube anemone killed it. Ours was close to a foot in diameter in a dull grayish-bluish color, covered in centimeter long little projections and really thin, much like the common elephant ear. on the upshot, when we fed it, even just cyclopeze, the whole thing would fold up for an hour of so untill everything got eaten. so, yeah, they aren't the prettiest choral out there, but in my opinion, they're a pretty cool and awesome beasty, and if i had a tank big enough, I'd really like one.
