i do vacuum the substrate every time. i will work on changing more water.
do you think that will help? and any idea why they just started to seem stressed? they always had great color and acted normally before the light change...
As i said, I can't diagnose issues, there could be something here like a protozoan, I don't guess at this. But there is no doubt that maintaining better water does go a log way to preventing and solving health issues of any sort. I was more aiming at the nitrate issue. While i wouldn't expect nitrates at 40ppm to cause this issue directly, I would expect it to have likely contributed by weakening the fish.
Every factor from water chemistry to parameters to water changes to plants to filter to light...all affect each other in a closed system like the aquarium.
