Hi All, We added 4 fish to our new tank exactly a week ago after cycling and testing the water. Today I noticed white spots on their fins. I'm assuming this is ICH but have never personally encountered this with previous fish so I cannot be sure. Any feedback is appreciated. I'm assuming quarantine is pointless as it appears all 4 have it. Am I correct? I'd also love to get feedback on best course of treatment. I know ICH needs immediate attention. Thanks!
