Alright two days ago I found three dead cardinal tetras. Not to worried as I added five a week ago without a quarantine (I know I get what I deserve!, but I observed them at the store for over two weeks. Yesterday lost four more (UGH more than just lack of acclimation) and one of my Corys. Today lost one more cardinal and one cory. Started treating with Melafix yesterday. One more of my corys looks bloated on his belly and not very active. None of the fish are eating much. Black neons all look good, Bolivian Rams also look OK although not eating much. One cardinal look like white covering on eye and is swimming more alone, another cardinal sometimes swimming at a 45 degree angle and hangin out near top. I am freaking out that this is either Neon Tetra disease or worse yet TB!
I did big water change (25%) on day one of episode. Today Nitrate and Ammonia are zero, I did not check them before water change. pH is High (more than any of my scales read, but cory's have been in tank for over a month doing fine till now) and the water is VERY hard also.
The corys all lost their coloring and turned pale a couple of days ago but it came back today. The cardinal with the white slightly puffy eye is the first specific symptom I have seen.
What do you think NTD or TB or something else
