Critter ID help

Any Idea what this guy is. Have about 6 of them on my LR. They are about 1/4" in diameter and 1/2" long. Thanks.

If they are hard tubes they are vermided snails, they put out a web to catch food. While they are not really harmful they multiple fast and they will cut your fingers to pieces and possible cut a fish if he is startled and bumps into them.

Wow, didn't know this! Knew the web part but not that it could cut you *_*

I'll have to google for better picture!


OP, did you start your tank with live rock or sand?

 

[squarebob]

I started the tank with reefcleaner mined rock. These showed up on a piece of dead sps that had some kenya tree coral on it. They have since migrated or multiplied to the LR many inches from the original.

I agree with Holley. Vermetid snails. They will grow everywhere. They are harmless, although very pointy and can cut you, if not careful!

I take a sharpe pointed knife and remove them, make sure you remove the base where the worm can hide!

I tend to leave them alone except if they are on my powerheads, then I break them off(which is when I generally get cut) I'll keep the knife thing in mind!

Yep, harmless, good filter feeders.

They only really become a nuisance if there are so many that they make the tank look like a haunted house with all the 'cobwebs' they string out to catch food particles.

And yeah the tubes are sharp, but most of us don't handle the rocks that much - just be aware of them.

I have yet to see any webs or anything come out of the end of the little critters. Is this a nocturnal habit?

 

[jennm]

Mostly, yes. Sometimes they 'fish' during the daytime too. That's probably why some folks opt to get rid of them because a lot of them can make the tank a bit unsightly.

I think they're cool - but then again I also like bristleworms and stuff like that so, um, yeah
