What the H### is this?

Agree with extraction if you get the oppurtunity, I wouldn't hunt him all night long.

When you do catch him(or them, since he probably isn't alone), just make sure that you keep them submerged as you extract them from your fish tank, because when they are taken out into open air, they morph into dragons. And the last thing you want is a dragon problem in your home.

On a more serious note, but only slightly, make sure it flushes down really well if you go with that disposal method. Last thing you want is a little tickle in the middle of the night....

On a really serious note, I am still laughing hysterically over this. This was great :lmao:

I could be wrong, but that just looks like a regular old bristleworm to me. They are the most unjustly maligned creatures in our tanks. They are detrivores that actually keep the tank clean. I've had some HUGE ones in my tanks (like AfricaOffroad's pics) that never hurt a single thing.

If you see the head and it has large "antennae" looking things then it's a Eunice worm. Those are a different story as they are very predatory and will rearrange your aquascape at night.

Agreed, without a head shot or tail shot at least there is really no way to tell for sure that is a eunicid.
