Looks like a flat worm to me.

Polyclad worm. Bad guy! Hope he was alone.

He was alone, I accidentally squashed him when I rearranged the filter, so now I don't feel that bad for him lol

If you smashed him in to pieces you may have another one soon. They can regenerate from just a part of the original worm. They usually are active only at night. Another reason to occasionally look with a flash light at night.

After I got your comment I took the filter apart and removed the squashed worm just to be safe, I don't want those things living inside my tank - particularly in my filter!!

I found a TON of these while trying to find out why my Zoanthids were all closed up.

I suspected they were nudibranches, but they proved to be extremely resistant to Flatwork eXit, which is supposed to kill Nudibranches very effectively. I also tried Lugol, and only ridiculously high concentrations (to the point of turbidity) killed them. After they died, my Zoanthids opened up, so I am almost sure these guys are responsible (I didn't see any other parasite at the bottom of the container that may have been killed by the dip, so I doubt it was something else). After a few weeks, significant numbers of these critters are back in the same places.
For more information they vary in size between ridiculously tiny (0.1mm or so) to small (2mm, perhaps three in some cases). They are almost transparent, and move a lot.
I obviously cannot add a gallon of Lugol to my tank, so I need to find a better solution. Right now, I am killing them one by one with a pin, and sometimes with a laser (I may need to get a bigger one for this to be effective).
They live only in the rocks that are near the zoanthids or on top of the zoanthids themselves. Small numbers don't see to affect the zoanthids much, but once they get to significant numbers they seem to affect them seriously. I haven't seen any effect on other corals.
Ideas about what they are or what I can do with them?

Hello,

This critter is currently hiding behind my protein skimmer so i cant get a better picture... But the attached pic shows something that came on a piece of rock that has a few mushrooms on it. It didnt move for over a week. Its probably hard to identify from this pic but i figured i'd give it a shot.

Thanks!

Those are harmless munnid isopods that are quite beneficial, eating detrtus

Need a better picture.

Jenn2208 · 11/17/2013, 08:56 PM

Found this before they opened this morning...anyone know what it is? And if I need to get rid of it. Thank you.

Shane5four · 11/17/2013, 10:57 PM

put it in tupperware to take good pics. Any clue?

archangel91 · 11/17/2013, 11:27 PM

Looking to ID 3 things from this pic.

1. The white spirals on the glass, from other pics in the thread I'm thinking possibly Serpulid feather dusters?

2. Near the center of the pic there's a small black with yellow center bug looking thing, no idea on that one.

3. You can't really see them in the thumbnail, but if you go to the pic on photobucket and zoom in at the rock near where #2 is, there's little bug looking things crawling all over. They're actually all over the rocks in quite a few places.

Hard to tell, might be a harmless stomatella snail. Take it out and put it into a cup of tank water and get some more pics.

some kind of bivalve. Harmless filter feeder.

The only thing I can ID is the spirorbid worms on the glass. The rest of the pic is way too blurry to ID anything else.

Thanks for the reply! I wonder then why is it that my Zoanthids close up tightly for weeks, and then, after a dense bath in Lugol that cleans out these isopods the Zoanthids open up again. Maybe I am killing something else that's the actual cause. There are other bugs which look somewhat similar to the isopods but maybe ten times smaller (so it is difficult to say they are similar, but they look the same shape and color) and that live intermixed with them, maybe those are the harmful ones and I am killing both species with my lugol baths.
I'll try to be more selective and see the results.

Kannon50 · 11/18/2013, 04:51 PM

Maybe one of you advanced critter guys and gals can help me ID this thing. also if it is good or bad. ....

i was told it may be a cucumber but i am not sure. its several differnt shards of brown, and kind hairy or has spikes. its loacted on the leaf thing

i didnt have tweazers untill now, i cannot find him now so am not sure exactly where he is, but when i find him i will be ready to pick him out if he is a bad guy.

your advice is much appreciated.

cloak · 11/18/2013, 04:59 PM

Kannon50 · 11/19/2013, 11:49 AM

Baby Mexican turbo?

No, collonista snail. Harmless and breeds well in captivity.

Nathonian · 11/22/2013, 04:48 PM

IDs please! Let me know if they're pests as well!

ReeferKimberly · 11/22/2013, 08:41 PM

What kind of pods are these? You can see how small they are since there are mysid shrimp in the video as well.

mrpergo · 11/23/2013, 09:49 AM

this was in one of my coral that I just bought and was acclimating.
Is it a bristle worm and should I keep it out of the display tank

Drakon · 11/23/2013, 10:19 AM

was going to move all my stock from quarantine to the display this weekend till I noticed these hairs on one of my snails, any clue what they might be?

Spionid worms would be my guess. If so, no worries IMO.
