Fin Rot-Fancy Goldfish
My largest (3") fancy goldie has shredded fins. This just showed up within the last week and may have coincided with my adding 2 new mates to his tank (he seemed fine then).
Should I treat the whole tank for this? The new tank mates are fine.
I did water tests and pH is at about 8 (too high?), salt at .04%, nitrite and ammonia at 0ppm. Temp is approx 74 degrees. I do have an under gravel filter (no gravel, I know-pretty!) and a HOT filter. Tank is octagonal, about 40 gallons.
THanks! This is the only goldie who survived my previous issues with dropsy, so I am trying my darndest to save him!
