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.

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. It is suitable for tanks up to size 10.5 gallons. Use 2 or more filters in larger tanks.
