I have a 45 gallon planted tank with a penn place Cascade 1000 canister filter. The tank has been up and running for about four years now and was stocked with 15 cochus blue tetras, 6 peacock gudgeon and 1 electric blue ram. I do weekly water change of 20% with a monthly water change of about 40% as well as weekly tests using the api master kit. The tank is kept at 77.5°.
About a week ago I noticed that one of the tetras had dropsy. I added some aquarium salt to the tank and after a couple days of the dropsy worsing I removed the fish and placed it in my turtle tank. I do this since in my experience dropsy in such small fish is always fatal and in my opinion being eaten by a turtle is better than suffering a slow death. The next day I found another dead tetra and gudgeon. I did water test and found that I had a large nitrate spike. I did daily 20% water changes. After 3 days there was still a large amount of nitrate. I did a large water change of 60% and added some zeolite to the filter.
I woke up this morning to find all of my tetras dead and the rest near the surface gasping. I removed the fish and added them to my 75 gallon aquarium. I removed the dead fish and tested my water. All water parameters are perfect.
I'm at a complete loss as to what killed my fish. Can anyone give me some ideas.
