I always fed my stubborn fish blackworms lightly a couple times a week to help with conditioning until now. I have lost so many fish this last week it's unreal and what of the fish that didn't get blackworms? They are thriving and some are ready to spawn. All of the fish died of the same thing, I'm still not sure what it was but no matter how much water I changed or what I treated with I couldn't get rid of it.
