Worm problem

[Jstn]

I had to reboot my tank 6 months ago to deal with a eunice worm infestations, I had 5-6 large 12" worms. Well the big ones are gone but now I am finding babies at night, these 3/4-1" worms that are very thin. I am 100% sure they are these eunice type worms that wreaked havoc a few months back.

Now I have a corris wrasse that is picking at the rocks all day, but my fear is th worms are nocturnal, while the wrasse is up for the night well before lights out.
I am wondering what options are left, and I found arrow crabs. My question is are they a good worm hunter, and are they fast along with nocturnal to solve this baby problem. I try to grab a few at night, but it seems there is always more, I figured might as well let something eat them.

Any comments or suggestions?

Thats really really bad..

Only info I could find on getting rid of them is removing the rocks :eek2:

Try to post pictures.. eunice has more of a centipede look to it unlike a bristleworm

I know its some form of eunice and I watched these devour my acan collection

the babies are tiny, but really long compared to width, I know they arent a standard eunice. They come out in the sand and literally there are many, I can get 5 a night but its getting tiresome.

I was looking for a easier approach.

Right now Im not experiencing anyloss, but after I had a few large ones reduce my acans from 16 price acans to one, I am not waiting for they to grow up...

Wow... thats a big investation...



They are pretty neat in their own little tank.. but just not in our DT...

Scary..

Hopefully someone will chime in as google seems to hate me today giving me no info.

Yeah I've only seen a few other cases not documented well. Most people have one big mean one, that would be much easier, that one in the pic was From before the purge.

I recall a while back reading that only one was ever found hitchhiking and it was in a huge zoo aquarium.

I now realize that article is WAY off...

Are they only in the sand bed during the day? If so maybe remove the sand bed? I know it's drastic but I'd consider it if they were nuking my acans. Maybe a sacrificial acan polyp in a trap placed on the sand bed? Just speculating....
