I don’t have nearly as many as that but right now I’m not able to quarantine due to my schedule. Having to check both tanks. In a few weeks I’ll be free but right now it’s impossible. But if need be I’d make it happen but this sounds goodSounds like brook.. so I had a outbreak and lost all of my clowns before I could take action… going fallow wasn’t a option for me as I have numerous large tangs in a 300 and nobody else showed any signs of anything.. in fact I have over 30 fish including anthias, chromis etc! Everyone else was fine but I lost the clowns.. what I did was treat my tank with ruby rally pro for 3 days as the instructions state and then did it again 2 weeks later and all is fine! I added new clowns after 4 weeks of the brook outbreak and my tank never skipped a beat! It’s been a couple months now and everyone is healthy and doing amazing!
