Digitate Hydroid

It takes a keen eye during late night hours to notice this particular creature. The first one I ever saw was in my refugium, and was a little thicker than a hair and about 1.5" in length when fully extended. If you watch Digitate hydroids for any length of time, you'll realize this is a thinking creature that is filter feeding similar to Fly Fishing. The fuzzy end will sway in the current, and the worm will reel it in in short jerks, only to release it again. It is extremely dilicate in nature, and interesting to observe. It can become a problem in some tanks, but it hasn't in any of mine. Reef-safe-ish. :)
