I started up a tank that I had run before. There was a lot of crud in it when I started it and (before I found these forums) I decided the crud from the old installment of the tank would benefit the bio-system of the new installment so I didn't clean anything. I ran it for a week before adding fish, but now I realize that wasn't long enough.
Anyway, my wife noticed this morning that one of our dalmatian mollies has a yellowish-brown spot on her side and her tail fin looks like it has rot. The fish is about 2" and the spot is probably 3/16" dia. I tried to get a picture, but the fish wouldn't sit still long enough to get a good exposure. I'm hesitant to treat with medication due to the fact that I'm about 2.5 weeks into the cycle and don't want to screw with the process.
BTW, this is the same fish that had babies a few days ago. Not sure if that has any significance, but thought I should mention it.
ETA: I should mention that I've been doing daily (sometimes 2x/day) PWC of 25%-50% depending on test results. Readings from this morning are 0.5 NH, 0.5 NO2 and 15 NO3. pH is constant at 8.0. 40g tank, 2 mollies - 1.5" & 2", 1 platty - 1", 1 pleco - 2" and 1 bamboo shrimp - 2".
