Aqueon Betta Filter
Aqueon makes it for betta bowls and aquariums up to 3 US gal; it needs an air pump, sold separately.
Aqueon’s small air-driven filter for betta bowls and tanks up to 3 gallons, hidden behind a natural-looking plant decoration. Air from a pump lifts water through a replaceable carbon and sponge cartridge, and the bubbles add oxygen.
Consider: Gentle air-driven flow for a betta, but it needs an air pump, sold separately, and Aqueon makes it only for bowls and tanks up to 3 gallons.
