Does anyone know what this is?

[Stevyn Perry]

I hope so. I'm hooked on these reef tanks. I'm sure I'll pick up some knowledge along the way.

I think there are some hard duster-tubes in the photo back in the crevice, but on the left side of the part you have circled, that' looks like an aiptasia to me. Can you get a slightly different angle?

 

[Stevyn Perry]

The duster is back where the arrow is at. Any other angle comes out real fuzzy for some reason . This is the best one I can get ya.

 

[Stevyn Perry]

The more I look those dusters are all over.

 

[Stevyn Perry]

I've looked high and low for close to an hour now, I don't see anything that looks like aiptasia.

 

[Stevyn Perry]

But I did find these?

 

[Stevyn Perry]

 

[mcarroll]

I trust your eyeballs! (aiptasia look almost nothing like those little red feather dusters)

Maybe the beginning of some sponge growth in that last photo?

 

[Stevyn Perry]

Thanks mcarroll, I will keep an eye on it just in case. I did find and zap 1 aiptasia this morning. Very tiny, hopefully the only one I have.

Once again I need help to identify a worm I found. Pretty sure they are bristle worms. The bottom picture has what's left of my small hermit crab they ate.

 

[mcarroll]

Common bristleworm. Leave them alone!

One of the best parts of your CUC.

They may have eaten the rot off of a hermit cram molt...unless the hermit died of a heart attack and started rotting in the tank. Then they might have eaten the hermit too. Not a live hermit though!

 

[Stevyn Perry]

So they had nothing to do with the crab dying, because he was the most spry out of all my crabs. But he was very small. I find it hard to believe because his shell was found up on the side right next to a hole where the worms we're hiding, and his legs and claw we're found on the other side of the rock in the stones under it.

 

[Stevyn Perry]

I thought maybe my urchin carried it there but it would have fallen all the way down we're it was at.

Nope, the worms were just hanging out or cleaning up. They are incapable of killing a crab unless it's the Godzilla of worms.

 

[Stevyn Perry]

Wow, thanks for the help guys, I'm sure I'll have more questions soon, thanks again.

I'm hoping someone can help identify what this is. I'm not new to fish tanks, but this is my first saltwater tank. My wife seen this yesterday so I took a picture of it. I just thought it was some sort of algea growing. When I got home today it was gone. It kind of looks like a starfish the more I looked at the picture. I just want to know is it something I need to get out of my tank when I see it next time. Thanks

I too believe it's a starfish. Take some more closer looks few days over it.

Asterina Starfish. Usually reef safe. After having them for so long . I would say toss it

 

[Stevyn Perry]

Found these in my tank, they move like a snail. They look like half of a clam shell.

#stomatella

 

[mcarroll]

Hm....how many critters are in that pic? There's a little limpet. I'm on a different monitor now and what I thought was a stomatella might be a bump on the rock.

I looked up "limpet" pretty sure that's what those are. Are they good to have?
