Camallanus worms in guppies (edit

[black ghost]

Flubendazole won’t do much. It’s a treatment for Cestodes (tapeworms). Camallanus are Nematodes, so you want Fenbendazole, or Levamisole or Piperazine.

I’ve always used Sterazin and it has always worked. No tank cleaning or water changes required. Just dose on the specified days, job done.

Thanks @black ghost . There are so many different bits of information out there, it's hard to figure out what works. The sterazin arrives tomorrow. They just have to survive until then.

Well an awful lot of fish have worms, but they’re only a problem if they have a lot of them, in which case the fish will starve. You’ve lost a few, but the Sterazin will hit them on day one, so hopefully the rest of the fish will be ok.

You should get this book. It’s a shortcut to everything you need to know...
