Two weeks ago I introduced nine white cloud mountain minnows into a recently cycled aquarium. One of them became somewhat lethargic and stopped eating, then died a few days later. The same thing happened to a second fish this past weekend, and as of today a third fish ignored food during feeding time. I can see no physical abnormalities, either when alive or on inspection after death.
Water parameters:
Ammonia - none detected
Nitrite - none detected
Nitrate - about 10 ppm (not certain -- I have a hard time reading the API color chart around 10-20 ppm)
Temperature - 70 F
pH - 7.8
dKH - 2
I don't have a GH test, but I found a study listing the tap water here in Pittsburgh at around 5 dGH (87 ppm)
They all seemed healthy and behaved normally before I moved them to the new aquarium. The move had to be stressful, though. We've just moved into our new house, and they got jostled a lot during the move across town. But if this is related to the move, why is this happening two weeks later?
Any ideas?
