Flatworm Description?

[mokujin22]

I have a few of these little guys in my tank. They are on the underside of rocks and extend a single tentacle about an inch to 1 1/2" long. It sways with the current (almost like it's filter feeding) and will retract when bothered. They almost look like white versions of brittle-star arms (with small feather-like nobs radiating out from the tentacle), only they get larger as you go towards the tip.

Sorry for the lack of picture. With my point-and-shoot, i have trouble photographing my frage; let alone something this small.

I don't think that they are acro flatworms... I believe that they are much smaller.

thanks in advance,
Tony

Sounds like some kind of harmless filter feeding tube worm, definitely not a flatworm.

Ya that does not sound like a flatworm to me either.

spaghetti worms maybe?

sounds to me like you have a mini britle star. they stay tiny, and will stick a tenticle threw just about any hole in the LR. alot times you only see one or two arms at a time. but then you say the arms get larger towards the tips. they could be Spionid worms.

take a look at these two sites and see if you find a match.
