I had a period where I thought there was an ick outbreak, but have been informed as of late that it's more likely a parasite called cammelanus. One guppy had small red hairlike strands coming from his anus. There was one strand, then a few days later two, then three. Eventually he became lethargic and sadly died.
Well I got a new guppy from the LFS (who looked just fine) and the next day what did I see, but a single red strand from his anus (and no I'm not talking about his poop as some have suggested!)
Anyways Diana at Fishgeeks was good enough to refer me to your site and I'm very interested in the levamisole treatment for the parasite. The only problem is that up in Canada where I am, there is very little availability for the stuff. I've got a farm feed specialist looking into finding some for me, but it's looking pretty slim. It appears that the current drug of choice up here is something called Ivermectin, which apparently kills the worms in sheep and swine faster. The problem is that I don't know if this medication can be used in the same way for my fish as levamisole can. The farm feed guy said I could get 400mg packets of piperazine dihydrochloride which he said was 97% pure. Would this work? If so, how would I use it i.e. dosage, duration, water changes, etc.
The guy needs until Monday to get back to me about whether he can get the Tramisol (i.e. levamisole) for me. In the meantime I thought I'd at least try something, so I bought some PraziPro, which I was told is good for flukes, tapeworm, flatworms, and tubellarians. The main active ingredient is <5% praziquantel. The guy at the LFS said the big aquariums (like Marineland in Niagara Falls) use this stuff, and so it should help with internal parasites.
So do you think this PraziPro might fix things up? If it doesn't can I go with Ivermectin or piperazine?
I should point out that all my other fish (besides the guppies) are eating and growing well. I know appearances can be deceptive with internal parasites however.
This is a case of uniquely bad luck : to hit one of the worst problems just one month into the hobby.
Per your questions: there is really no good alternative.
PrazlPro is a wide-range dewormer which is totally ineffective against roundworms. As an experiment, I actually tried very high concentrations of Praziquental on a live nematode -- it did not react in any way. Scrap it, hope you can get your money back.
Ivermectin: in theory should be effective, but I don't think that there is a methodology around that can be followed. Ivermectin is known to be toxic, so experimentation will be quite dangerous. See, for example the footnote here.
Fenbendazole: in theory should be effective. I'm aware of cases where correct application of fenbendazole failed and claims that it is actually effective; if you absolutely cannot get levamisole, explore in this direction.
The best course of action is to get levamisole *somehow* and asap. Possibly you have a friend in the US who can get it for you, possibly some levamisole-based dewormer designed for a different animal is available in Canada. is Avitrol available? Look here:
For nematodes capable of direct reproduction the infection affects the entire tank. Unless treated, chances of a total wipeout are pretty high. Note that it takes some time for the worms to mature, on the order of 2-3 weeks, so the disease may take a fairly long time to kill every fish.I should point out that all my other fish (besides the guppies) are eating and growing well. I know appearances can be deceptive with internal parasites however.
The appearance of worm in a new guppy sounds a bit strange to me. Most likely this means that all guppies at your lfs are infected, and possibly much of their other fish. The fact that they are apparently aware of the problem and are still selling is troublesome.
One thing that you absolutely must not do is to bring any new fish into this. You need to handle the disease first.

I have it shipped priority and get it is 2 - 3 days.
Here is the saga of an aquarist in BC that had camallanus worms. The ultimately successful treatment he used is near the bottom of the story.

He could not get levamisole HCl, but he did find something that worked. I'll let you read it.
Its encouraging to see in your posts that some have had success with the Fenbend. I certainly hope it works in my case as I appear to have little choice. I'm starting the first dose Sunday am. I thought I'd do a big water change first and try to get as much of the Prazi stuff out of the tank in preparation. I hope this stuff works quickly, another guppy died today and I could see the worm exiting his body. I've got both the worm and the body preserved in a baggy in the freezer for future autopsy if needed. Hopefully the body count won't rise any further.
L-isomer is active against helminthes with 1-2 times higher active efficiency and lower toxic and side effects than tetramisole. It is a broad spectrum anthelmintic with a very good activity against roundworms, hookworms, whipworms, and strongyloises stercoralis. It is an immunomodulator and has effect on rheumatic disorders.
