    Myth: Bettas can live in tiny bowls

    People think “In pet stores they keep bettas in tiny containers… the bowl I am getting is a castle compared to that. My betta will be so happy.” OR “In any case, bettas live in small stagnant pools in the wild and, therefore, it is perfectly appropriate to put them in tiny bowls/tanks.” Unfortunately, these are not a good suppositions.

    The Truth

    The small containers bettas are kept in the stores are chock full of chemicals to keep bacteria, fungus and parasites at bay. They are unhealthy places for any fish to be in, and they are not meant to be long term homes.

    Bettas do live in shallow pools in rice fields in Thailand. But, these puddles are interconnected And can extend for miles. If the puddle the betta is in gets stagnant, the betta has the ability to (and they do indeed) swim to another puddle or, if it is the dry season, jump up to 6 inches into another pool (or even from puddle to puddle until they reach one that has appropriate parameters).

    In addition, the water they are in is continually refreshed with rainwater and decaying matter. In an aquarium, they are stuck and it is up to us to refresh the water and keep their tanks clean and non-toxic through routine partial water changes.

    The minimum size tank that you should keep a betta in is 3 gallons. 5-10 gallons is ideal.

    The smaller the tank the more you have to work on upkeep.


    Myth: Bettas can live without heaters

    The Truth
    Bettas originate in Thailand. This is a tropical country and they are tropical fish. The mean temperature in Thailand has been 27C (80F) over the last fifty years. Bettas do need heaters if not kept in a tropical country.

    For those of you who like to see data I refer you to the Thai Meteorological Department.

    Myth: Bettas do not need a filter
    Bettas breathe oxygen from the surface so do not need a filter.

    The Truth
    Yes, Bettas do have labyrinth organs which allow them to rise to the surface and breathe oxygen, but this is just gives them supplemental oxygen. Bettas also absorb oxygen through their gills. A filter not only filters the water but also supplies added oxygen to the water. ALL FISH INCLUDING BETTAS NEED A FILTER.

    Because betta have been bred to have elaborate fins, the filter flow should be gentle. It is best if you get an adjustable filter and run it at minimum flow. If you find that your betta is struggling against the flow or intake of your filter you can baffle it in several ways.

    Myth: Run your tank for a day and then it is safe for your betta (or other fish)

    The Truth
    All fish need a working nitrogen cycle. In a cycled tank there are several types of good bacteria that converts the ammonia (that your betta is continuously producing from breathing and living in the tank) to less toxic substances. If you add your betta to the aquarium before you have cultivated these bacteria, then the ammonia and other toxins will rise rapidly and you will have continuously be doing water changes to keep the water safe for the betta.


    Betta Care

    1) Bettas require both a heater and a filter.

    2) They should be housed in tanks of 3 gallon or more; 5-10 gallons is ideal.

    The smaller then tank, the more onus is upon us to keep toxins at bay. A smaller tank requires more testing, more water changes, more care in not overfeeding, changing an adequate amount of water on time, and cleaning all waste and food immediately.

    3) There should always be some hiding spaces for them to chill out if they do not feel like being on display. Betta love real plants or silk plants that are soft. Plastic plants can sometime snag and tear their fins so should be avoided.

    4) By and large, male bettas should be kept alone with no companions. Large snails and shrimp can be kept with bettas, but there is a chance they might become lunch. Males will fight with any colorful or long-finned fish because they see them as competition. Bettas can be in a community tank if the tank is VERY large and there are many hiding places, but this take a little vigilence at first to make sure it is working.

    5) Females can be kept in communities if the tank is large enough and with sufficient hiding spaces but even here, there is always a possibility that one will become aggressive. You should expect, at first, there will be some fighting or aggression while they work out the hierarchy of the sorority.

    Of course, like humans, fish have differing personalities and you CAN have a laid back male betta who coexist and interacts very nicely with other fish. But, this is the not the norm. Most bettas are aggressive especially to other pretty fish with flowing fins. They like to be the prettiest fish in the tank.
