It's more ignorance than cruelty I think. People don't realise the actual needs of a betta bc of media and ill informed pet store employees. Plus, since they're so pretty, they do make nice accessories! ;) That's why next time I have the disposable income I'm getting a betta TATTOO!!! lol
As long as yours are kept well and you help spread the word in your locale, then you are doing your part. :) WE know these containers are a bad idea, but we need to tell kids and their parents that they are as well!!
