I think I found one?

I think I have a hitch-hiker. It looks like a small starfish, and its a blueish color. But, this is the first time I have seen this thing. I poked it, and it is squishy, but it didn't move. I am going to show you various pictures below this message to identify if this thing is an octopus or not. I DON'T WANT IT IN HERE IF IT IS AN OCTOPUS!!

Pics:

sorry about it being blurry.. that's as best as I could get.

It looks more like a squids head.

If you poked it and it didn't move, then it wasn't an octopus. I can't tell from the pictures, but it almost looks like an Ascidian.

 

[Maxi]

It dissapeared..? Lol.. I did poke it a couple more times after posting, and it didn't move. But it did dissapear 5 minutes later.
Does not look like an Ascidian at all, I just looked threw pictures in a yahoo search since I didn't know what it was But now the thing just dissapeared..

The pictures are way to blury to do more than guess. Squishy and didn't move very fast, could it be a sea hair?

 

[Maxi]

Alright, I got a clearer shot, but its not as close. It decided to move to the top part of its little crevice.
I can see 4 arms and it defenetley looks like a starfish there, but I'm not 100% sure because I can't see the rest of its body.

I think its an asterina starfish...? Is that bad?

 

[Grins]

Looks like an asterina yes., Some are fine, some eat corals.

All my corals are doing great, so I'm guessing this one isn't bad. Thank you!
