I have never personally experienced this problem, but have seen pictures. I have a 29gal tetra tank with 15 neons, 6 bloodfin, and 2 serpae tetras (used to be 7 and lost 5 in less than a week.) Water parameters WERE:
Ammonia 0
Nitrites 0
Nitrates 10-20
Ph 8-8.2
So I did a water change yesterday and took out 8 gallons, but this time I replaced 2 of those gallons with RO water mixed with conditioned tap water. The water parameters today are the same but ph dropped to about 7.4 overnight! (Was not trying for such a quick change!, which is why I only added 2 gallons RO!!)
Anyway, today all of a sudden 2-3 bloodfins have something that appears as though their mouths are rotting. I attached a pic (crappy from my phone sorry!) so is this columnaris? Could it happen over night like that?
