It mat actually depend on the species. I have one 1996 journal extract issued by a crew at John Hopkins University (Graczyk/Fayer/Cranfield) whose data indicate that C. parvum inoculated fish, lizards and snakes revealed no life cycle stages of this protozoan in any section of the digestive tract at 7 days post inoculation and 14 days post inoculation, even though by day 4 PI fecal specimens of all inoculated tested oocyst positive. The conclusion of that study was that no gastrointestinal infection was possible in lower vertebrates although they may retain the oocysts.LondonDragon said:
You'll be fine where you live dave as your water comes from the Dee via Bretton WTW, same as my house but only just as down the road from me is fed from the Alwen.Dave Spencer said:Who cares about fish. My kids have to drink that stuff.
I have done a water change on both tanks today, but I can`t see there being a problem.
