TBH, I'd rather concentrate on the fact that there's people posting here who think a half gallon/quarter gallon is an adequate space for a betta.
Like, I get there's a few really experienced fish folks who use gallon-sized containers and keep the fish clean and alive? But if you haven't kept bettas for years and learned all there is to know..
How many of the under-a-gallon defenders end up posting in the sick fish forum a few weeks later? How many of the sick fish posts are from beginners with a gallon or less? The proportion speaks for itself.
But that's me. Good luck combatting the forces of corporate stupidity, though.
