Betta Bowl

[FishFanatic04]

I agree. A betta can be kept happily in a small filterless, tank, provided there is enough room. I prefer at least three gallons as I have seen betta happy for a while in a 3 gallon filterless tank. A heater however, is a must, as the majority of disease I have had with bettas has been stopped by having a heater. Just make sure if you make the decision to go filterless that you are on top of water changes every other day.

Another food for thought here. My tap water ammonia is 1.0 ppm. Filter-less Bettas and every other day water changes would not be a good thing. There are so many variables. [disclaimer: My Bettas have filters.]

I don't understand. Are you saying that bettas need at least 18L to swim in, whilst you give yours a 10L bowl?
