Here's another update from this morning. I checked my main tank. The other fish looked good still, except a white lady had a red spot and red lips, and she was acting lethargic. When I netted her, she even didn't try to move out of the way at all. So I pulled her into the QT tank with the other sick girl, since I didnt have any other place to put her.
I'll share some photos of the two sick ladies, as well as a video of everyone else in the other tank.
I added the med trio on Saturday in the main tank, so in a few days I should be in a place I can do a water change in the main tank, since the water looks pretty ugly and dark.
I have the meds for the QT tank on order to arrive by Thursday. No stores near me have the right medicine, so hopefully I can keep yellow sick lady alive until they arrive. In the meantime, I went ahead and added another dose of Maracyn to the QT tank when I added the white sick lady in there.
I'm feeling pretty down about all of this. I have a lot of learning still to do, and I hate that these poor fish are part of that learning process. This is my first attempt at fish, and I had the main tank cycling for a long time and consistently had great readings for over a week before adding fish. I guess next time I will be more patient before adding a fish, and I'll start fish out in a QT tank even before moving them into an empty tank.
Appreciate you all for helping me with this, @Colu @Chick-In-Of-TheSea @nabokovfan87. Hopefully I can save as many of these guppies as possible...!
Not sure why my photos are posting upside down...
I'm also confused about the red gills. Both my main tank and QT tank are testing at 0 ammonia...
