Stomatella snail would be guess as well.

I thought it was something bad at first, and was going to take it out. However, after looking closer I'm leaning toward it being a baby (or maybe shell-less?) snail. So for the time being I left him in my DT...

...but if anyone sees any signs of this being something bad, let me know.

Thanks

Sump it. It could be a nudi. hard to tell, or maybe spaghetti worm. Any tentacles or other characteristics that might help our than picture.

Ok, I'll admit I'm a little spooked about all the aiptasia posts/pages I've read, so this might be a little stupid, but is this pic of an aiptasia? Only seen this one, so I was kind of thinking no, but noticed some weird critters the last couple of days......WTF1.JPG

I'm actually thinking its a feather duster now. Right? Just not as colorful as a lot of the pics

Yep, feather duster.

[deputydawg88]

Any idea what this is? It seems to have quite a long stem.

Pineapple sponge. They are common in new tank set up and generally most go away over the short term. But they are good for the tank. Like most sponges they filter feed and help clean the water.

Hello again. Spotted this on the rocks.

I've taken some pics of a few of the other shrimp as well as the sick shrimp, tho I haven't caught a pic of one RCS and one of the adult ghosts was being annoyingly discreet hiding in the back middle of the tank at the very hardest place to get a decent photograph of it but I tried. If people can comment on shrimp genders that is useful info too, especially for any non ghost since I don't want too much of a population of them...Prefer the colorful and more interesting (rather than creepy lol) looking shrimp.

Please help! I just don't want to sit by and watch the poor thing die! She even molted today or last night and it didn't emerge yet! Any advice or idea (except euthanizing because she doesn't yet seem like she even knows it's in her, although since her molt she's been a bit less active but I think that has to do with unhardened skin) would be helpful! Not sure how to put up the pics I have of her/it...

I think you might be better of making a separate thread for your issue. To upload images, on the reply page there is a "Manage Attachments" button below the reply box in the additional options section, you can use that to put the pictures up.

This forum is for salt water tanks. You'll be better off finding a forum dedicated to fresh water tanks.

Being trying for hours to identify these "white tentacles coming out of the rock" - picture attached.

I've browsed all the pictures of aiptasia, and spaghetti worms and they don't look similar to me. If its aiptasia I don't see the mouth, center.

Its growing on one rock, 2 couples from the bottom, and another one from the top.

If you look closely a couple of the tentacles in the center looks like a polyp.

Can you please help with diagnosis?
Should I leave them or try to take it out?

Thank you so much in advance!

[Ron Reefman]

andywar, that is not aiptasia or spaghetti worms... no way.

Is your tank a recent set up?
Was the rock in the photo bought as a 'live rock' from somebody or an LFS?

My fist guess, and it's just that, a guess, is that it's some kind of branching sponge. I think I see some 'holes' that look like the vent holes sponges have. In shape it looks like it could be algae, but I don't recall any white/translucent algae. But I could be way off.

I'm sure somebody else will jump in and maybe do better than I.

[alcimedes]

so they actually fluoresce bright green but the phone didn't pick it up, they look clear in this photo. Any chance they're baby green button polyps?

Or are they something else?

[A777flygirl]

Top one looks like a tube worm of some kind?

The bottom one looks like a white Venus fly trap?

Can't find any pics like it? Bristleworm?

Thanks!

[alcimedes]

A777Flygirl, Christmas worm maybe for the bottom one, not sure about the top.

They look more like Colonial Hydroids IMO. These aren't necessarily bad, but they can be quite irritating it they come into contact with any corals. Definitely keep your eye on them.

So I have some colonial hydroids on the base of a frag plug elsewhere, and those hydroids have the typical tube and then filters at the top. Those hydroids are also the brown color I see in photos of hydroids.

Whatever these tiny green things are, they've shown up now in three different places. I'll keep my eye on them and see if they get any larger, or if this is it.

For scale, they're maybe 1.5mm in total height, if that.

The hydroids I have on my other frag pictured below are easily 6mm of tube, and 1.5mm of filter at the end so these are much smaller for now. The hydroids are also brown, and don't fluoresce under the blue lights.

These are def. hydroids at the base of this plug, right?

[AlSimmons]

Yes.

And now he's size of a softball. Been this size for over a year I'd say.

Heh. Mine disappeared into rock cave for 3 months until it was too big to hide and had to come out. It's a relentless film and coralline algae grazer. I love it.
Mine came on Caribbean live rock. Yours?

Gulf Live Rock...rock was full of life (macro and micro).

Hello, just getting back into the hobby. Was hoping for some help. Can anyone ID these and should they stay or go. The second and third pictures seems to be some sort of tube worm that produces a web like string to trap food and debris.... Thanks in advance

First picture is a sponge, the other two are vermetid snails.
