ApistoQueen Posted April 14, 2022 Share Posted April 14, 2022 Over the last 24 hours I've lost 7 of my original 11 black neon tetras. From what I can see, they start flashing, then swimming erratically before losing bouyancy control and eventually dying. I can't see any outwardly consistent symptoms other than fin rot in one or two of them. I've had them for about 2 months and they share a planted tank (with airstone) with 2 apistos, 2 plecos and 12 cardinal tetras which were added in the last week. All other fish seem fine. Water params: - Ammonia/nitrite = 0 - Nitrate = 10 ppm - Buffer = 80 ppm - Hardness = 150 ppm - pH = 6.8 - Temp = 79.5 F Link to comment Share on other sites More sharing options...
