well i think you can fix stupid. or i should say ignorance. i mean we all start somewhere and then educate ourselves into a better understanding of fish care. however i think tanks that are in most restaurants are just thought of as part of the decor. if the fish die they write it off, go out and get another one and there it is . fixed. they treat them like they would a pot, plate or glass. not like living creatures. i really hate to see aquariums in places like that. very depressing in most cases.
