For most diseases its safe to rule them out after two weeks. Internal parasites can go unnoticed for months though. The other reason they are such a PITA is there can be absolutely no external or behavioral signs or the signs are irregular. Below is angelfish I bought through a local club at the end of last year. This fish and his 2 buddies had camallanus. Unfortunately this is also when I was lax with quarantining and treating preventatively. For years I excluded locally bred fish I got from other hobbyists from quarantine, since they were always in the best of health.


The picture is from a week after I had gotten it. I was starting to suspect something after he would not eat for a few weeks. Yet one of his buddies was eating everything and all the fish seemed to stay in good body weight. I didn't expect anything seriously wrong with him till he suddenly died 5 weeks after I had gotten him. He was swimming around then dead 5 minuets later. When the host dies the parasites try to make a break for it in the hopes of getting eaten by a scavenging fish, so realizing the issue after he died was pretty easy. Both the other angels also had the worms, though at much lower levels. However none of them behaved the same.

I am also in uni. I used my one of my schools microscopes to take a video which is on youtube if you are interested (search camallanus). I left the dead fish with one of my professors cuz they thought it was really cool . I wasn't upset about the fish being dead since it was really cheap, it was the 30 other fish that I ended up having to treat.

OK, so I finally went to the local Tractor Supply Company. Unfortunately the only Levimasole they has was an ointment for horses. However, they did have Fenbendazole in liquid & powder form. Does anyone have experience with Fenbendazole?
Also, the only bird dewormer they had was a liquid with active ingredient called dichloropiperazine...does anyone have experience with this stuff?

Thanks,
Ami

I'm getting ready to treat some fish I have for nematodes of some sort by using fenbendazole. I plan to use the 1 gram safeguard dog wormer packets and diluting it down. It's my understanding that fenbendazole can't be dissolved in water, so I planned to dissolve my powder packets in a small amount of acetone (sounds bad, but is quite safe for fish) and then mixing that with water to get the meds into suspension. If you have access to a liquid, then that might be easier to work with, but try to find out what the "inactive" ingredients are, they are the ones you have to worry about being safe with the fish. That's why I'm using safeguard, the inactive ingredients are apparently safe for fish since many people have used it.

I planned to treat my tank water with 2ppm of fenbendazole. A 1g packet of safeguard contains 22% fenbendazole (220mg) and will treat 110 liters (29 gallons) of water to 2ppm. To dilute it, I planned to dissolve my powder into 29oz of tank water. This would make a solution whereby 1oz of solution will dose 1 gallon of water to 2ppm. Therefore, to dose a 10 gallon tank, I'd pour in 10 oz of my solution; a 20 gallon tank would take 20oz of solution. I planned to use some of the treated tank water to soak some dried bloodworms in so that the fish would get some medicine internally.

I'm picking up my meds today, I'll let you know how it goes when I treat some fish. I have some wild caught mosquitofish that will be getting the first dose just to be sure I got things right, but I'm fairly sure of my calculations. I might do them tonight.

Ok, here's an update. I dosed the first set of fish yesterday at noon so it's been a little over 24 hours now. I dosed the DGs instead of the mosquitofish. The acetone was a bust, it didn't dissolve fenbendazole any better than water does. Still I shook it up really well and poured in the amount for the tank. Some crumbs settled out on the bottom and on decorations, but allot of stuff went into suspension in the water and clouded it up a little. I was pretty concerned about the stuff settling out, but after a few hours the crumbs slowly disappeared. So I guess the meds do appear to dissolve given enough time and water. I'm feeding them dried food to force them to swallow a little tank water with it. Can't really see anything different in the fish, but I'll know when I get a "sample" from them in a day or two. As long as I don't see any living worms, I'll consider it a success. The fish seem unaffected and are acting completely normal so far.

For the next batch of medicine, I'm going to try a different solvent.

Thanks for the update.
I found a dealer on e-bay that sells Levamisole HCl Powder. I got 10g for $15 and he gives free shipping. Hopefully it'll arrive by Wednesday and I can start the treatment on my 55G.

Cheerio,
Ami

Levamisole is soluble in water so you should have no trouble with that. Maybe I should have gone the levamisole route, but I couldn't find any locally; plus, it's just going to get harder to find in the future, so may as well find an alternative now.

I found the solvent I needed today. It's DMSO and I was actually able to go in and buy it off the shelf at a hardware/farm store. I put the packet of wormer into a small jar and added 1 tablespoon of DMSO. Some of the material dissolved instantly, but allot of larger crumbs were still left intact. Since the MSDS for fenbendazole says that it is "freely soluble" in DMSO, I assume that the stuff that didn't dissolve right away was some of the "filler" material that makes up 78% of what's in a pack. I added some water and most of the other stuff dissolved then so I feel that the medicine anyway is suspended in the water now which was the whole point; I don't care about the filler but it would be more comforting to see everything dissolved.

I dosed two tanks and they got way cloudy, more so than the first tank. Plus there weren't as many crumbs, so I guess the DMSO did its job. It's only been about an hour now, but the fish are still acting ok.

Let us know how that ebay stuff works. It looks kinda sketchy to me. If it really is levamisole its defiantly not very pure. His suggested doseage is also 0.8 grams which is 8 times more then mine. Another thing is my stuff is 90% levamisole HCL and its yellow not white.

Levamisole is hard to find, I have been using it for years though and it is such a fast and effective medication that it is worth it to me. The stuff I have and still used expired back in 11/09 it still effectively treated those angelfish about 6 months ago. I've kept it in a very small glass jar in the dark and intend to keep using it till I know it no longer works or a good deal on levamisole pops up.

My dealer was chrisyang1155 on e-bay. I will definitely give a negative feedback and flag the fella in case its a hoax. You're right, finding levamisole is hard...I'm going to see if I can find a friendly vet I'd like to stock up on the stuff.

Aquabid.com has levamisole in the medicines section. I purchased mine from mvp and would recommend him. Good luck with this. One of my betta girls is fighting off these sttupid worms and sadly, I've already lost two bettas and a platy to them. :(

For fenbendazole, it's best to give via medicatted foood so you would need to make up your own medicated pellets or bloodworms. And it's said by some that fenbendazole is only effective on the larva of the worms, not the adults.
