Ok some people buy impulse bettas and thats alright to a certain extent. But Too much of anything is not a good thing. IMO I see too many people buying bettas on impulse using excuses like "oooh he's so cute he wiggled at me at the pet store". I have seen bettas that I would really like to buy (I even posted a thread once) but I always walk away. I dont know, Hope no one takes this personally, but one buy after another, after another can become animal hoarding, which is a serious issue that needs to be worked out. I used to have a neighbor who came with a new pet snake at least once a month. His house smelled something horrible. according to him most of them were "rescued" from previous owners who no longer wanted them. I dont agree with impulse buys. or "rescue" buys. Only buy a fish (or any other pet) if you already have everything planned out and have a set mindset when you walk into the store. Sure, we may slip - but dont let it become a habit.
