I'm throwing my whole house away because of what I just found in my tank...If I have to see it, so do you!

Don’t try to pull it out, if it breaks you get more. With the large black one, it’s tunnels weaved vertically throughout that rock, it was in every bend of it. No way we could’ve pulled that out intact.

I like the worm...

I am pretty jealous, I follow a tank thread that has one, always some lovely pics of it :)

Update: Send help, it has mandibles and tried to eat my tongs! Also, there isn't three...THERE IS FRIGGIN FOUR.

Please ignore my hands shaking, those things are mighty scary when your hand is just centimeters over the water. :rolling-on-the-floor-laughing:


OMG, I'm bookmarking this. That footage is extraordinary. Well done! And RUUUUUNNNN!

Okay, maybe that's dramatic, but I now have a severe case of the heebie-jeebies.

I have Hidden Cup Coral hitchhiker in my 40-oz pico tank. I was trying to get some pictures of it, so I turned the flow off and fed the coral. I regret that decision because almost as soon as I did, these creatures emerged out of the dark for the first time. There isn't just one...There aren't just two...There are THREE of these in my 40-oz pico tank (the display is only 20-oz). One of them even seemed to try to bite my Hidden Cup Coral??

My guess is some little Euclid or Dorvilleidae worms. Either way, I don't want to turn my back on my tiny reef for fear that one is going to come out of the water and suck my brains.

Look on in disgust with me!

Here is the first mini-monster...



Here is the second that seems to try to take a bite of my coral (second 48)...

You should - it really doesn't take a lot of width/space for a trap. There's a plethora of commercial ones (bristle worm traps) available, but the basic premise is a small container with an opening just a bit larger than their diameter, and some bait, such as a small piece of clam, shrimp, or such. do a search for some pics. Place it near the opening of the burrow after lights go out. Repeat this a few times until they "get used to it being there with food" and then one evening a few hours after lights out check it and remove it to a separate container to see if you've caught one. Try to ensure you remove the entire worm - they do regenerate from sections left behind...so to speak.
Cheers,
Ray :cool:
Awesome, thanks for taking the time to write this up! I’m going to try it out and hopefully I’ll be back with picture of the captured critters soon!

Hmm. Yep. Interesting "little" critters, but I wasn't willing to devote a system to a single specimen. This one was in a 40 breeder frag system, and I just happened to spot it between the filter and the side glass when I walked by a few weeks ago.


That's not a Bristle worm:

THAT'S a bristle worm!

I’m Not going to post an image of my worm as that would be a violation of the rules.

The 2nd video the feelers of the worm got stung by the coral nematocysts, it wasn’t trying to eat the coral.

Someone needs to train these worms to eat Aiptasia and Mojano and then they will be a popular pet store item.

I was walking around in a lagoon in Tahiti, actually I was snorkeling and decided to stand and walk out because there were hundreds of these creatures laying around amongst the sand and algae. I didn’t go back to that place afterwards. The worms were not aggressive but I didn’t want to be mistaken for a lunch item.

So happy I've never had one of these in my tanks, but if I did I would be tempted to set up a large species tank for it and feed it constantly to see if I could set the record for world's largest monster worm.
