Fish Acting Half-Dead After Water Change
Like the title says, I was just changing the water in the tank like I always do and all of a sudden all my CPDs are floating around like they're about to die. Specifically, not being able to stay balanced upright, infrequent bursts of swimming, hard time fighting the slightest current, and laying on the bottom of the tank. Some are back to normal, relatively, but what the hell cause it?!
