As you probably know, the Betta fish is a very popular fish species because of its hardiness. It can thrive in almost any conditions, as it doesn't require much. This is the main reason people choose this species as pets and eventually end up stuffing them in tiny fish bowls. Although they can survive in such a small place, your primary goal shouldn't be just to help your fish survive, but to house it in the best possible way. As a result, it will live longer, won't be prone to diseases or stress and will always be a fun companion. So don't be stingy if you want to keep a Betta or two in the future. Start by getting it a proper fish tank instead of a fish bowl. Setting up a Betta fish tank is neither expensive nor difficult and practically the only piece of equipment you'll have to invest in is a good fish tank filter. Fish bowls lack this piece of equipment and it is the very reason most Bettas don't thrive in them. How do you expect your fish to live a long and healthy life if its water isn't clean enough to dwell in? Getting a fish tank filter will greatly improve the life of your fish.
