Have been searchig for praziquantel but don't know if it is sold in the uk on monday evening I had some kusuri left over and dosed the tank the senegal had quite a few on it head and body on tuseday today I can see a few worms on it. My polli is in a cave at the moment so cant check him to see if there is any improvement as he had the most of the worms the kusuri is almost finished so will need to get something if it dose'nt clear all of the worms up
