Hi guys. So I noticed some small white patches on one of my female scarlet badis, and she was flashing. Seems to be fungal, but with no fluff. My tank includes 5 amano shrimp and a blue velvet shrimp, so I looked for a gentle medication that wouldn't bother them. I'm dosing Melafix and Pimafix, which both say they do no harm to inverts. However, my blue velvet has been swimming all over the tank frantically all day, which he never does. (This is day three on the meds). My amano are looking a bit agitated as well. Aside from the one female scarlet badis with the issue, I have four others that look to be in excellent condition, with no symptoms. But also... I have a school of 8 white cloud mountain minnows who haven't been doing well. They are either flashing or lethargic, since before the meds... but aside from that, they look perfectly healthy, with no external signs of illness. No spots, patches, velvet, redness around the gills, nothing. A few have died, and they look pristine, gently rounded bellies and all. The tank is fed on flakes and microworms, along with the occasional algae wafer. I have a fluval power filter (waterfall) oxygenating the water, and as far as I know, if there was a lack of oxygen, it wouldn't cause flashing. The tank is planted, the pH is around 7.6, and there is ZERO ammonia, nitrite or nitrate, and I have been testing regularly. I have dosed appropriately with melafix and pimafix for two days, and today will be the third day of dosing, but I'm almost afraid to do it because of the way my blue velvet shrimp is behaving. Thoughts? Advice?
