Hi everyone. I am new around here.
So I acquired a school of 16 glowlight tetras - 8 from Petco and 8 from my LFS. Two of them died the next day even though I drip acclimated them for 2-3 hours.
A week has passed and then 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, the following day 5 of them showed the same signs. Yesterday (the day after that) one of them died. I'm not sure if it was the one with the discoloration and more displayed the same signs.
I'm thinking it might have been the water change that affected them BUT 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 nitrites.
I looked around the internet and it SEEMS that they got neon tetra disease/pleistophora OR columnaris. 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. 5 of them remain in my tank and 8 of them are in the hospital/QT tank. 3 of them are in the freezer; I'll try to return/exchange them to Petco. I am afraid some of the 5 remaining are showing the same signs today. I dosed melafix just in case its a infection/bacterial thing but I doubt it will do anything.
Notice the difference in color between the middle tetra and the rest:
