55 Used to worm tropical fish
Verified Purchase

By on 18 September 2015

Sorry for the off-label review, but I wanted to give advice to other fishkeepers in my situation:
Having lost half a dozen fish to camalanus worm, with all fish worming treatments failing to treat the problem, I learned that Levamisole could be used to kill them - but at the time of writing, you cannot get a fish-version in the UK. I had no idea if Harkerverm would be safe to use on fish, but decided to try as I had nothing to lose, and I have had great success in treating tropical fish. I did lose one already very sick fish during treatment, but all others I have treated have survived. Harkerverm definitely, directly saved the life of one fish I caught with very early symptoms (visible worms, lethargic, but the fish still eating), she was back to normal behaviour after 48hrs and shed the last worm after 4 days. I treated at a rate of 3.125ml Harkerverm to 20l tank water, leaving the harkerverm for 3-4 days before doing a very large waterchange and 100% gravel vac. I continued to feed the fish, although I found they often refuse to eat on day 1. I was recommended 2 treatments of levamisole 3 weeks apart, so this is what I have done, and I have had no fish show any symptoms since using this treatment regime. I have used in hard, neutral and soft water at the same rate - and I have treated live bearers, loaches, panda gara, siamese fighters and neon tetra.
Viovet offer a speedy and efficient service - which is perfect, as I feel you need to start treatment asap after noticing the first worm protruding from the fish, to have any chance of saving it. However, regardless, if one fish in a tank has camalanus worm, you need to treat the whole tank and all fish in it.

Chicken,s eating but losing weight

Chickens eating well but losing weight and dieing

  • VioVet Staff

If your chickens are affected by worms then this should be a good product to use. However given the information you have supplied I cannot be certain this is the case and so ideally you should get your vet to check your chickens and tell you if worming is a sensible plan, or if some other treatment might be more appropriate.
