  • The only time they become aggressive is if there is more than one male swordfish in the tank.
  • The aquarium filter helps remove decaying matter, excess food, fish waste, suspended particles, etc. preventing cloudiness and the accumulation of toxins in the tank.

An aquarium that’s safe for fish will read 0 ppm (parts per million) of ammonia, 0 ppm nitrite, and around 10 ppm of nitrate.

Generally, the fish for an aquarium of this size should not be an over-breeder or a fast-grower. A 5-gallon bowl with some live plants would make a good habitat for a single male Betta.
