Camallanus use of piperazine directly in tank

[fishloverintraining]

I have camallus in my tank. A guppy is not wanting to eat medicated food (febenzazole and/or piperazine). He is bloated and gills are starting to flare, along with stringy poop. Has anyone use piperazine directly in the tank? I see reference to it but can't find anywhere if it actually is effective this way.

Welcome to Reef2Reef!

Are you positive of the diagnosis for Camallanus? Did you see actual worms emerging from the anus?

I've never used piperazine in the water. I have used Fenbendazole at 7.6mg/gallon a week apart for three treatments. However, it has a strange mortality issue - it kills some species of fish outright, and doing a water change won't stop that, the fish die within 3 days of treatment. I don't know which species are sensitive to this, most are not, but darters, some catfish and flashlight fish all will not tolerate it.
