Hi guys. Im having a mini ich outbreak since 1 week ago. All fishes been eating well and haven’t lost any fish yet. I notice 2 white dots on my borbonius fin 4 days ago. And its lost the entire fin today. Curious what can cause this. No nipping as far as I’m aware. It’s eating well. Been hiding when lights are at 100 pct. But out swimming when it’s off.
