JOR Betta Sponge Filter, 6 x 5.5-Inches, Underwater Center Aquarium Filter, Works for Tropical Fish & Breeder Aquarium, 10-25 Gallon, Perfect for Fry & Small Fish, Must-Have for Aquarium Hobbyist

  • FILTER SPECIALLY DESIGNED FOR BETTA, FRY & OTHER AQUATIC PETS — Betta, fry and other small fish will NEVER get stuck up into the filter. These fish, especially Betta, generally don’t like vigorous currents, they prefer calm and steady water. This filter is designed to have slow current to easily let betta, goldfish, discus, dwarf cichlids, guppies, and krill fish, continue breeding and spawning comfortably.
  • PROVIDE SUPPLEMENTAL FOOD FOR FRY — The minor bubbles that are created by this sponge filter creates a nominal current, adding in bubbling water. This will encourage them to continue breeding and spawning comfortably. Also, the sponge filter makes a home for fish food supplementing their daily dose of diet or food intake.
  • REPLACE THE TRADITIONAL HOB, CANISTER FILTERS — Gone are the days when you got to change the cartridges and filter media almost every week. The handy filter by JOR will do the same job economically and quickly.
  • PERFECT FOR LARGE TANKS — Our 6.2 inches long and 5.5 width filter requires an air pump and airline tubing (sold separately) to work. These create numerous minute bubbles for increased oxygen flow. Simply connect an air pump to the top-center of the filter, then place it in your tank. Please note, the base of this noiseless filter is not weighted, so you may need to weigh it down. Use 2 or more filters for community fish tanks.
  • EASY TO WASH & REUSE — This low-cost sponge filter by JOR can be used multiple times. Instead of tap water, use water from the tank for maintaining it, during a water change. Simply rinse and squeeze a few times, until you see the water run clear from the sponge.
