Good betta fish care dictates giving your pet a container that is sufficient for the fish to swim around at least a little bit. Bettas can naturally survive inside the little jars they are usually sold in, but this can be far from a healthy environment and bettas in these tight quarters may fade in color and grow sluggish. Bettas don't need a huge quantity of space, but somewhat room to swim, plus a decent quantity of surface area for your fish to obtain gulps of air in are recommended. As a suggestion, a 1 hour to 2 gallon fish bowl can be a good option.
