What is this?
Its the whiteish tube like thing, it was longer when i noticed it. It retracted awfully quick when I shone a flashlight looking around the tank like 5 minutes ago. Any ideas? Let me know if I need to get a better pic.

Thanks to all who knows or attempts to know.

Some sort of worm but without a clear picture it's hard to tell. Does it have bristles?

Google "peanut worm". If it looks like an elephant's trunk, that's it.

It looks like it could be a peanut worm. Nothing to worry about.

peanut.

I googled peanut worm and could find anything that looked like it and I'm working on getting a better pic. should be able to get one up soon.

what is a peanut worm?

Peanut worm is harmless (although some argue that point because they bore holes in your live rock). They eat detritus (or something nasty anyway), they are nocturnal, and they don't hurt anything. In fact, I think they're cool and it's fun to find them.

To me the most distinctive feature is the outer skin of the worm looks like an elephant's trunk to me. And when it retracts, it looks like it's collapsing in on itself.

yea, thats wut it looked liked when I first found it. how did it get there? how could it have survived the ammonia spike when it was cycling?


I think i got a clearer pic, its really hard to tell cause its so hard to get a clear pic at night. as long as its harmless, with regards to holes in rocks, which is cool, i'll leave it alone for now :)

I'll check those links barbara, thanks.

It got there most likely in the live rock. You'd be surprised what kind of critters survive the tank cycle.

Personally I love the diversity that hitchhikers bring to my tank. 'Course I wouldn't say that if it was a mantis shrimp or something like that!

haha, well i'm just surprised cause I the tank hit 4.0ppm amonia in the cycle and i had a couple of small brown polyps survive too, plus the water was a milky color as well but i still dont know why it did that.

also, i read those links and its sounds like it has been identified.

Enjoy it. I had one that would extend at least 6-7 inches, and I haven't seen him since I broke my tank down and set it back up. I'm hoping he's just deep in a rock somewhere. I look for him sometimes; I miss that dude.

aww, i am sorry. well, he scared the crap outta me when I saw him retract, I can now hold a flashlight at him and look at him. it just sits there, i think he, in total, extends about 4 inches, give or take a few as he is weaving in and out of the rock on one rock
