I rescued 3 scats from a guy who couldn't keep them. They are only small ones maybe 3 inches in diameter and have only been in freshwater. I know they are supposed to eventually be in brackish but I have no plans on converting..is there anyone out there who has successfully kept scats in freswater for life? I don't like getting rid of fish these guys are cool id like to keep them but is a lifetime in freshwater a DEFINATE no?
