Ich, How did this happen?
As many of you may have read, I have been having trouble with my cycle. I was doing a large PWC (60%) due to nitrite problem and noticed my oldest and largest Giant Danio has what appears to be ich. What I can't figure out is how it could have gotten in the tank, as nothing new has been introduced into the environment in over 3 weeks.
Still not ENTIRELY sure it's ich, none of my other fish (3 other Danios and a pleco) are affected, and we keep the tank temp at approx. 78F. From what I've read, ich is not "happy" with high temperatures.
Since only appears to be affecting one fish, I am wondering if I should euthanize him, since I am unable to begin treatment until at least Thursday (two days from now). I am also not currently equipped to set up a quarantine tank, and will not be for a bit of time yet.
