So far, 2 fish affected. One cardinal tetra, one rummynose tetra.
A cardinal tetra was first. It had a loss of color, specifically around the dorsal fin. The area was slightly raised and white-ish.
One day later, a rummynose showed problems. It also had a white-ish raised spot right behind the dorsal fin. There was a white fuzzy spot on the dorsal fin itself, too. About the size of an ich grain, but mildly fuzzy. The fuzzy spot on the fin could be removed by stroking the fin with the tip of my finger, but the area on the fin where it was attached still showed discoloration.
Both fish stopped schooling with their shoals.
These fish went from having no noticeable symptoms to "omg, remove from tank!" in about 24 hours.
Tank is 37 gallon with a Rena XP2. 0 ammonia, 0 nitrite, ~5 ppm nitrate. 7.6 pH, which is on the high range for these fish, but I wouldn't think unreasonable.
The cardinals have been in the tank 2 weeks, and the rummynoses for about 1 week.
Any ideas what might be up?
Here's a picture of the rummynose. The white spots are visible in the picture, but they're not very clear. I've had fish with ich before, and those fish had very distinct white spots that were each very small. These spots are not the same size, and are mildly fuzzy.
