Note - Please do not take this as the be-all-end-all of betta keeping. It’s just a few of the myths that get thrown around. If you’d like more information on the habitats, biology and care of these fantastic but misrepresented fish, check out these links! If you wish to keep a betta, the least you can do is your research! They are a little life who depends on you, not a novelty or decoration. Just be aware there is quite a bit of advice out there at caters to the myths.

The Plight of the Betta (Includes a section on “betta vases”)
I made 2 Pinterest boards for betta tanks. One for tanks, kits and equipment that bettas might do well in/with and another for stuff that may be marketed towards bettas but are not very good at all for them or their owner. These aren’t exhaustive lists, but a point of reference to go from.
