Like that page of supposed 'tanks'. There was this .5 (maybe less) 'tank' that gave instructions on how to care for your betta. I believe it said something along the lines of :
"your betta should be fed 1 time per week, and change the water 100% once a month." Then it goes on to saying how bettas came from Japan and how they lived in the footprint puddles of soilders who were at war... o__O;
First off, bettas come from Thailand and Vietnam.... Second...just..ugh.
Needless to saym I sent them a nasty (but polite) email. No response :P
I also had a hard time with a lady at petsmart who had a female betta in with like 6 goldfish... o___o I told her that the betta couldn't be with the goldfish because of the high ammonia and the cold water. She looked at me funny and said "Betta's don't need heaters! They live in puddles in the winter, silly!"
I responded back "ok....You know where they come from right?" She said "They're from like China right? Like way up north in the cold?" -___-
I took the girl out myself and asked for a new betta cup, filled it, put her in, and on the shelf. Poor girl was skinny and had ammonia burns all over. :(
