Hi there
Over the last 3 days, I've lost 3 of my zebra danios and have a 4th looking like he might go soon. The first two I found dead on the filter intake, but the 3rd was floating with two vertical cuts, bleeding from both. I currently have a 4th with a single vertical cut, bleeding a little, and swimming with labour.
All of my water levels are good, ammonia 0, nitrites 0, nitrates >5ppm. PH is around 8, water is a bit hard but that's normal in my region. All other fish are in great shape. Ideas of what might be going on?
