That's pretty much what I have been told, that one is extremely active tooWhat redness? I just see a mild roan-ish tint around its entire head. Natural color variation, I think.
Last time I checked, ammonia 0, nitrite 0, nitrate under 5 ppm. I cannot do a water change nor add prime cause it would neutralize the medication plus I just don't feel like shaking bottles all day lolWhat is your logic between not being willing to test while your tank is medicated?
Neither meds nor carbon (or lack thereof) should affect those parameters you would be testing for. They are either bad or good.
The Oto looks healthy to me.
