Keeping fish in a glass box isn't natural neither, but we do it anyway.My issue is simply that I've seen no evidence that lower salinity is "better" for fish, unless it is part of an active treatment regimen (hyposalinity). I don't know if lower salinity is any "worse" for fish, but it isn't natural so I personally would stay away from it. The problem I have is online vendors shipping fish at low salinities, creating more work for me to bring my QT's salinity up to my reef,
