Pix & ID: Critters that come in your rocks: the good and the bad.

[deputydawg88]

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.

"White tentacles coming out of the rock" not identifiable with most critters pictures

"White tentacles coming out of the rock" not identifiable with most critters pictures

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!

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.

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?

Can anyone help with these?

Can anyone help with these?

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!

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.

When I first got my hitchhiker urchin, he looked like this

3 months later

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

...and 23 days later for me. Confirmed urchin

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.

What is the recommended way to remove either?

Sponges are great, never a reason to remove them. I believe those snails are fine as well, but double check.

I'd be happy to have the sponge, it's a good thing for the tank.

The vermetid snails aren't necessarily harmful, but if their numbers go up, they can become an annoyance. I've never tried to get rid of the ones in my tanks and they haven't been an issue. But others have found them to be a problem.

They do look like a colonial hydroid.
