Day 2 of treating the Q tank with flubendazole and I see this floating by in the current. P. fangi & e sp. redspot for fish. Tank has been set up for a week. Bare bottom, rocks from other tanks, filter media from an established tank but only hard bio-media, no sludge. It's barely a cm long. What is it? Where did it come from? From inside a fish???

You sure this is a worm and not say uneaten (undigested) bloodworm? Are they alive? Can you get a cleared photo?

Having said this, two things:

1. The problem, if there is one, is p.fangi. They are least healthy looking on my end too, and in fact some look skinny and make me think of internal parasites... albeit I do not know if what you see are the parasites that cause the problem. And while I did not see any external problems like you described on mine, it is known that fish weakened by internal parasites is prone to secondary diseases.

2. If I may so suggest: consider not quarantining different groups together, even if they come from the same store (unless you know they come from the same tank)... I got burned with this a couple of times very badly, years ago, and now consider this to be absolute not-to-do thing.

There's only one so far. Most definitely alive. These pics are pretty good if you can open in a viewer that will let you enlarge them. Of course I agree with your point about keeping them separate. It just wasn't an option.

Here is what I want to see on the photo: It appears that the worm is segmented, Annelida (rather than round, Nematode) but I cannot be quite sure about this...almost but just not enough resolution... Segmented worms are normally not parasites. OTOH, leaches are Annelida.... ?!

Maybe a good idea to repost this on r-f.org, ColinT has a good sense of critters like this...

Looks for me like a mosquito larva. Jim. Must not be a bloodworm, it may be an other species. You can see in the photos the tufts on the abdomen.

mosquito larva was my first guess.... but notice that it can kill smaller balitorids just as parasitic worms... if Anthony fed them live bloodworms he was deeply wrong, balitorids are not gobies. Want to call him and ask?

I sent a pic to Dr. Charles Harrison, from whom I buy flubendazole, his reply.

"This is a larva of one of those white fly guys that you see in the fish room from time to time. Totally insignificant in the parasite category. Great fish food though. Just enlarge the image so the segments of the worm can be seen. The tail looks much like that of a mosquito's. There needs to be a way to breath air or hold on to the water surface. They are much like Blood worms but without the color."

Thanks Mike & Jutta!
