I have been all over today to try and get the wormer plus, however none of my LFS's stock it or anything like. The closest I could get to a treatment for gill fluke was Interpets Anti Velvet and slime treatment, which also claims to kill flukes. I bought some but not sure if I can use it with the other meds I have used.
The fish are all pooing normally, as far as I can tell. I hove noticed that the 5 Neons in the tank are just hovering near the bottom and just making sudden twitchy jerky movements, and I have a male guppy who is just sat on top of the filter at the surface and only moves if I touch him with something.
Gill flukes are hard to get rid of as she have to kill the young as they hatch. You can be treating a long time with some meds.
The wormer plus you have to treat once a week for 4 weeks to kill the young as they hatch.
