I'm with you. I've never lost a saltwater fish yet, not to stuff it came in with. I'm real careful where I buy, and look the fish over very carefully before I leave the store. I've had a few ich breakouts in a couple of decades of doing this, but nothing I haven't been able to solve. Seems to me saltwater fish come in cleaner; and that a bare tank is productive of stress. Being able to revert to natural behaviors immediately I think has some value.
