Are you referring to this fish Rottbo?
http://wetwebmedia.com/snowflakemoray.htm as being sold as the FW Moray?
If that were the case, I would not be surprised. My LFS guy sells plenty of fish and he'd declare one species wouldn't need salt while others were full blown SW species and would be completely wrong. (poor Xenopterus naritus, bronze puffer)
Just make sure you know which species you are looking to buy for your tank. But like stated, either of these species (provided the salinity is right) will be decent fish for your tank... minus the taste test.
