I have never been a fan of fishbowls but especially not for bettas! They are TROPICAL fish & need their water to be kept at a constant temperature between 74-80 degrees Farenheit. I know petstores will tell you that they make a fantastic desk ornament in a tiny cup or vase but it is NOT ideal conditions for them to live in! Bettas need to be in a minimum 3-5 gallon tank that is cycled, filtered, and heated. It's all a big myth that bettas live a good life in bowls. They need space to swim & grow. It's also a myth that they lived in little rice paddies. The truth about those paddies is that they're enormous bodies of shallow water, and the water is in constant movement, thereby constantly eliminating the toxic effects of the ammonia, nitrites, and nitrates. They jump from paddie to paddie in order to find a more suitable home.
So please don't get sucked into the fad! Give your bettas a heated, decent sized home!!!!
