Honestly (no hate please!) I'm starting to develop the opinion of 'anyone dumb enough to fall for something THAT stupid without first doing research (research should tell you its a ploy, you shouldn't even have to type in "bottled betta water" to know that's bull) kinda "deserves" to be ripped.'
Okay, so they don't deserve to be ripped off as such, but if they did their research they'd know its bullcrap, so really, who's to blame? The guy who knows jack about cars, doesn't seek a second opinion and buys a broken car? Or the con man that sold the broken car to him? Personally I think they're both to blame a little, granted the latter more so but anyone in their right mind usually heads to google AT LEAST before diving into something head first when they know they've got no clue about it, whether it be cars, fish, horses, mortgages etc..
These days the internet is pretty easy to get hold of and if you can't spend 5mins on google then expect to be ripped off.
Personally I feel more sorry for the betta that's ploped in 250ml of "betta water" because "its better for him to be in a tiny amount of this water than a decent size, filtered tank with normal water, geez don't you know anything?"
Them people bug me and if they get ripped off, who cares? Ain't no money out of my pocket.
I don't want to argue, just stating opinion; no hate please.
