Steev, Thanks.....I had no idea that cold water fish could get it. Is it usually non-fatal in cold water fish though, since it grows so much slower?

They can carry it for a long time too because Ichthyopthirius grows and reproduces more slowly in colder waters. It also infects at a generally lighter level because it has trouble finding a host when the fish are less crowded. Steev
