Hi, Just wondering if you have got rid of the worms yet? I've found an ebay international seller in austria who posts worldwide and he is selling sera nematol. I used it for my fish after trying 2 other treatments which failed and it got rid of the straight away. Here's the link: http://cgi.ebay.com/Sera-med-Professional-Nematol-10ml-/360186452681?pt=de_haus_garten_tierbedarf_fische...
