Unidentifiable critter

So I just done my first water change and must have pushed this little guy out my live rock I thought it was a stone to be honest till I saw it slowly crawl back to my rock then scaled it back up the rock and in to a hole

Could someone tell me what it is and if it's good or bad I plan on putting in some easy to care for corals and a couple of small clown fish over time

It's a little bivalve.

 

[craigpaterson]

Are they ok for reefs etc ?

 

[Lionfish Lair]

Yup. They're safe. It's probably a cockle.

I just googled imagine it and it don't look like the images lol do u have a link to learn about them the google images of bivalve look like clams lol

This thing is about the size of a peanut but can move quite quick to be honest is it good or bad do you think ?

isolate it for now if you can see it and then get positive id , if its any of the bad things that look like that you'll be happy you did

 

[Lionfish Lair]

It's a plainer version of this. Take it out and take a picture.

Your looking at the hinge, in your picture. It opens on the other side.

 

[craigpaterson]

I will find it again and isolate it and get some more pics and post them

 

[craigpaterson]

Got some more pics

 

[Lionfish Lair]

Yup, it's a bivalve, like a cockle.

 

[craigpaterson]

So it's ok safe to keep with corals etc

 

[Lionfish Lair]

Oh yes, they're pretty cool.
