I just recently got one that looks exactly like jakano's pictured above. I don't know anything about them, except that after reading this thread, I want more!

It is starting to extend a feeding sweeper here and there - only like 5-6 total right now, but as I was looking at it very closely, I noticed a little 'arm' extending from the center, it reminds me of a porcelain crab, going in and out, in and out. Is this normal? It's not at all similar in appearance to the feeding sweepers, it looks kinda like the long arms of a spaghetti worm, except these are short and they move back and forth like a porcelain crab does with his fans.

Should I be concerned? It looks healthy.
Thanks!!

Look up barnacle. It is fine, and interesting to watch.
