Fenbendazole

[Carl Cardarelli]

Can anyone tell me the dosage for a 600 gallon tank also the pro's and con's if known(is it gentle on fish was Praziquantel). Been battling a fluke like parasite for 2 years praziquantel powder, copper and Hypo down to .011 has not killed it slowed it down for a few days but that's it. Prazi been done several times and Hypo twice and still in tank, fish only tank with a few eels (Zebra).

Thanks

Ed Noga's book gives the dose of 2 mg/l fenbendazole (7.6 mg/gallon) once a week for three weeks.

I can't remember if I mentioned to you, but I've had some serious reactions in fish to Fenbendazole in the water - I lost a whole group of flashlight fish, and in another case, it killed some darters. A public aquarium reported a list of freshwater fish that this is also toxic to - cory catfish and some tetras.

Thanks for info , just to let you know started to drop salt again going to shoot for .010 for 45 days bat fish fulled with the parasites with occurred over night and rest of the tank starting to rub against rock. My big Mappa Puffer died and a blend I had for over 2 years starting to wonder if I should just give up? Thanks for all your advice and help!

rubbing into things thanks for all your input

The batfish is showing scrape marks from all the rubbing. I wish I knew what those white spots are! The puffer had some issue with its mouth, or am I mixing it up with another person's fish?

What about trying a skin scrape on one of the fish? You can get a cheap cell phone microscope for around $16. If you could even determine if this is a protozoan or a worm parasite (or both?) that would give us a better direction to go.
