I posted a couple of days ago about acquiring a school of 16 glowlight tetras. Two of them died the next day I bought them even though I drip acclimated them for 2-3 hours.
A week has passed and yesterday one of the fish looked abnormally discolored. I disregarded it since I just did a water change and that might have stressed out the fish. Well, today about 5 of them show the same signs.
I let my water rest in a plastic container for about 3 days. Added dechlorinator and the usual amount of fertilizer for the plants. Temperatures, alkaline hardness, and pH for both tank and replacement water were the same. Nitrates are about 10-20ppm, 0 ammonia, and 0 nitrates.
I looked around the internet and it seems that they got neon tetra disease. I had something similar happen to another tank not so long ago where it wiped out my school of rummynose and cardinals. It stuck hard and fast, killing all 20 tetras in a period of 2 weeks.
I just pulled out a plastic container to quarantine the discolored fish. Just have to wait for the water temperatures to equalize to move the affected fish and do a 50% water change.

Notice the difference in color between the non-affected tetra and the others.
