Midnight hitch hiker's hunt (ID please)

[mrhasan]

So I got bought some new frags today and suddenly, for the first time, I have witnessed hitch hikers in my tank.

1. I guess this is asterina but not totally sure (since I read that non-reef safe asterina-lookalike stars exists). So I took it out (saw one only) as soon as I have spot it. ID anyone?



2. This is the cool spotting. I got a hammer frag today and there's this two small opening between the tentacles and from that, something that looks like porcelain crab's filter feeders coming out and going in. I tried looking closer to it but I can't seem to find any porcelain crab within. There's just two opening and those feeds comes out and goes in. ID please.
