Another Jake Posted November 1, 2020 Share Posted November 1, 2020 Tank: 20L, Planted, hang-on-back with sponges and bio-media, air stone, 75F, almost no algae. pH: 7.5 | Ammonia: 0 | Nitrite: 0 | Nitrate: 20 | KH: 5 | GH: 9 For the last few days, I've had about a single death per day... Cardinal Tetras, CPDs, and Ember Tetras... It's random. No visible symptoms like ich or fungus. Just each morning I'm finding one fish at the bottom either obviously struggling to live or dead and being eaten by shrimp. ...The shrimp are doing great. Right now I have one Ember that might be breathing fast. All the other fish seem fine. The CPDs are even doing that little dance that they do with each other. Please let me know what you think I should do. Should I treat the tank and just hope it's something unseen? Is 20 too high for nitrates for these fish? It's not spiking anything. It's all very steady. I feed a mix of flakes, bug bites, frozen daphnia, live baby brine, and occasionally dried tubifex worms. I don't think I'm over feeding, but I could be wrong. Any help is much appreciated. The schools are down to their minimum numbers now and I'm not adding anything until this is sorted out. Link to comment Share on other sites More sharing options...
