Betta Fish Tank Care

It is vital to maintain the healthiest environment of the tank for the survival of betta fish. You should try to provide them with a living environment that matches with natural habitat. For proper care of the tank and betta fish, you should consider the following guidelines:

  • Usually, the 5 gallons size of the tank is suitable for a healthy betta, and a minimally 2.5 size of gallon tank is appropriate. But don't make the mistake of keeping them in small bowls.
  • Ensure to cover the tank appropriately with the lid because betta fish are amazingly high jumpers and climber pets.
  • Don’t fill the tank with a total volume of water.
  • Try to maintain artificial light in the daytime in the tank and off the light during the night to regulate their biological cycle naturally.
  • Never keep the tank in a place where direct sunlight comes, as elevated temperature enhances unwanted algae growth.
  • Set a decorative atmosphere in the tank to sustain a native and natural habitat. To create a beautiful decorative environment, put small artificial plants, rocks, and driftwood in the tank. Betta fish likes to hide and move around in between plants and rocks.
  • Avoid placing the two male bettas in the same tank.
  • Adjust and maintain the temperature of the tank regularly. Betta pet likes the water temperature of 78-80 degrees. So, place the heater in the tank according to tank size.
  • Keep the filtration system in the tank to eliminate the waste materials of fish.
  • Maintain the 7.0 pH of water in the tank because the too acidic and alkaline environment is not good for betta fish.

Betta Fish Feed Care

As a pet parent, you must regularly take care of the appropriate feed for betta fish. You should give a balanced and nutritional diet to ensure a healthy life for your little betta pet. Protein-rich foods are the most necessary nutritional requirement for betta fish because they are carnivores, and pets and like to eat meat.

  • Healthy protein-rich fish pellets are usually good and recommended feed for the betta.
  • Betta loves to eat freeze-dried bloodworms and brine shrimp as an occasional diet. It also likes to eat krill and daphnia.
  • 2-3 pellets of feed per day are the perfect and ideal diet.
  • Black worms, small earthworms, red worms, bloodworms, and mosquito larvae are safe diets for your betta.
  • Never overfeed your betta because overfeeding causes constipation, gastrointestinal bloating issues, and swim bladder problems leading to other adverse effects on the tank’s water quality.
  • As betta fish are surface eaters, keeping the tank's surface clean and unblocked is essential.
  • Don’t give extra feed to your pretty betta for compensation when you are not at home; they can live without food for 14 days like humans.
  • Avoid giving your betta other tropical fish.
  • During stress conditions, betta fish don’t want to eat, especially when they are new at home.

Betta Fish Habitat Care and Cleaning

Another essential thing for making your betta happy and comfortable is providing them with a clean environment. Larger tanks are easier to clean than small tanks. You must not remove all water from the tank during cleaning. Remove half of the water while you are cleaning the tank. Distilled white vinegar and bleaching agent are good choices for cleaning the aquarium. Avoid washing the tank with soap. You should consider maintaining the nitrogen cycle in the tank. The water used in the tank should be free of chlorine. You can eliminate chloramine, ammonia, and other heavy metals like zinc from aquarium by using betta water conditioner. Don’t add distilled water to the tank.

If you properly feed, clean the aquarium accurately, and maintain the tank conditions effectively, your betta fish can increase the growth up to 3 inches. I suggest you feed your beautiful betta daily, check the water quality weekly with the kit and ensure to clean the filter on a monthly basis.
