I got this from another awesome forum member some months ago but forgot to get an ID, and I swear there is a thread for getting ID's but I can't find it now. So feel free to move this, mods, but I would like to know what this is, if anyone can help. Not with the intention of selling it but just for me. Thanks all in advance for looking!
yeah I would have thought chalice or something too except it pretty much always has its feeder tentacles out and it's not bumpy at all, smooth and a little translucent. The individuals are about the diameter of dimes or pennies right now. And it's growing on a piece of hard skeleton that has long, straight grooves in it like someone ran a comb across it.
