Would fenbendazole, 2 mg/l, dosed weekly for three treatments, be an effective treatment for flukes? My understanding is that Noga said this is an effective treatment for intestinal worms, but would it also work for flukes?
You said you don’t recommend using DMSO to dissolve it, correct? How would you recommend dissolving the powdered fenbendazole?
I saw a couple wrasses yawn in my other qt tank. They’ve been treated with prazipro, but their qt tank was seeded with biomedia from an established tank, so the concern is that the bacteria consumed the prazipro faster than it could kill flukes. I’d prefer not to move the fish to a new sterile tank to avoid stress on the fish.
I would not recommend fenbendazole at all.
If praziquantel isn't working, you could try hyposalinity.
The yawning symptoms may just be behavioral, even flashing/scratching may not be an issue if they are done infrequently. However, if those symptoms are moderate and are combined with rapid breathing, congested skin mucus and listlessness - then I begin to worry more.
