Hey all, i recently bought some more live rock, the first night i found a what appears to me to be a baby brittle star fish, i was shocked! i heard about hitchhikers, but i never thought that i would get a brittle star on a rock, now i dont have to buy one, but what has amazed me is that i came across what appears to be what i think a baby feather duster, but i am not sure if it is. as i am still learning this hobby. i have attached a pic of it, and if anyone can tell me what it is would be greatly appreciated, at first i thought that it was aiptasia so i shot some aiptasia and it went back in the rock. and after a few minutes it was back in the water grabbing what it can, i was feeding my corals and it went crazy opening and closing. thanks all
