it is all marketing, the almighty dollar. just like comercials for toys, they attract children, and who can say no to that face. there are so many parents that know nothing about fish and just get them because theyre kid wants them, without knowing or giving a crap about the proper care and treatment of them. my daughter once asked me for a tatooed fish. once i explained things to her she felt so bad she almost cried. IMO, it is our job as parents to help our kids understand these things. I would never discourage my child from any of her interests, but i do try to take the responsiblity of informing her seriously. if she has an interest i am not familiar with, i consider it a good idea to find her someone who is to learn from. unfortunately fish arent for everyone, although it is portrayed as such. point is not everyone considers research before purchase a good plan.
