Yes, that's perfect...although it raises even more questions. So no one has attempted a study with a temperate fish like a Catalina Goby? And if 0 samples excysted at 12-17C, does this mean that ich cannot replicate at those temperatures? But any enysted samples can survive for up to 6 months at those temperatures and then hatch if warmer waters are encountered? Curious...
Is it still only in the Eastern Mediterranean, or has it spread in the aquarium trade? And copper treatment is ineffective?
No - this is a ciliate that is found pretty widely spread - I've gotten it on temperate coldwater fish from Japan. Copper works, but you have to catch it early because it is so slow to effect a cure, if you catch it late, the fish die before the copper has time to work. It looks like Cryptocaryon, perhaps a bit darker. Rather than distinct white spots, it presents more like congested skin with mucus.
Well, I always dose copper for 30 days, so that time frame deals with it, not sure about the two week dose though.
