Sigh, I was making my rounds and checking my tanks, when I noticed a nasty ich infestation in my 29g. I have three baby juruparis in there who have it the worse, along with some tetras. My zebra danios and loaches don't seem affected yet, but I immediately started medicating the tank. I really like my juruparis, but they seem pretty far along. I don't know how I didn't catch it before, but it seems like it hit pretty fast and hard. How far along is too far along?
