Identifying stuff

[vonohlen_1]

I am 3 months experienced in the hobby and I have a few questions. The first is almost a clam looking thing on an empty shell I got from the lfs, the second is almost like small red tube things, the last is like a little tan something

1) Looks like a baby tridacna clam. If it's still alive I would secure the shell on to your rock work and shoot it with a little phytoplankton everyday. Very cool hitchhiker.

2) Likely turnicates or sponges. Not enough detail in the photo. If it has a web coming out of a hard tube then it's likely a vermited snail. Don't worry about it.

3) Is it mobile or sessil? If mobile it could be a nudibranch and should be removed. If it doesn't move its probably a sponge or turnicates.

Thanks a bunch I thought that looked like a clam and I was happy to see that. I will try to take care of it it's a shame I only noticed it about 4 days ago. I have another item. Is that green coralline or something else I should be worried about?

I am sorry if I double post but it's like my last post disappeared I am new to this app. But one more thing to identify I think it's green coraline, but if not is it something I should be worried about?

The first one is probably just some sort of bivalve. I'm not really sure about those red tubes in the second picture, but that tan thing in the third picture is a Vermetid snail.

How do those red tubes feel to the touch? If they're hard they might be Foraminiferans or possibly Vermetid snails as well.

Okay so the one item is a clam and he is alive! I put the shell on my rock closer to the light and he opened and when I shadowed him he snapped shut!

So is this green coraline or something else I need to worry about/be aware of I will post a pic of my tank in a couple hours. Thanks a lot for the help!

It's likely just green algae. Nothing to worry about. All part of the process with dry rock. Next it will turn grey. Then shades of purple coralline.

You're very lucky with the clam. If it has bored itself into the shell/rock then it's a rare find. You normally only find them in the ocean like that. They're also pretty expensive and require strong lighting.

 

[CuzzA]

Yeah. See if you can get a picture of its mantle.

Okay I will take a pic when he opens he's been shut for a bit while I was working on my tank. Here is my tank btw

He maybe opens his shell 1mm but not enough to see in yet
