After adding fish recently, I’ve had an ick outbreak and lost all but a couple of the new fish as well as my older fangs that I’ve had for years including my large achilles and sailfin. Is there anything I can do to help them fight it? All seem to be eating pretty well still, including pellets and nori daily. I’ve used up most of the metro that I had from the past. I will definitely be quarantining all fish in the future but I hate that I can’t seem to stop this
