Basic Requirements for Owning a Betta Fish

Betta fish require a suitable tank with a minimum size of 5 gallons, clean and conditioned water, and a heater to maintain an appropriate temperature of around (78-80°F or 25- 27°C). A gentle filter and a proper diet consisting of high-quality Betta fish pellets or frozen live food.

Betta fish need adequate space to swim and explore while they are often sold in small containers, these are not suitable for long-term housing. Ideally, you should provide a tank with a minimum capacity of 5 gallons (19 liters). A larger rank offers better water stability and allows for a more varied environment. Ensure the tank has a secure lid to prevent jumping.

Tank decoration should appreciate a well-decorated tank with hiding spots and resting places. Substrates use fine gravel or sand as the tank's substrate, as it is easier to clean and won't damage the Betta's delicate fins. Plants live or silk plants offer hiding spots and resting areas for your Betta. Avoid plastic plants with sharp edges that could tear their fins.

Tank size for Betta fish requires a minimum tank size of 5 gallons to provide them with enough swimming space and to maintain stable water parameters.

Regular tank maintenance is necessary for Betta fish to perform a partial water change ( about 20-30℅) every week and clean the tank decor and substrate as needed to maintain water quality.

Bettas are carnivorous and thrive on a varied diet. Feed them a combination or high. Quality Betta Pellets or flakes as a staple diet. Supplement their meals with frozen or live foods like brine shrimp, blood worms, or daphnia. Feed them small amounts two to three times a day, only giving them what they can consume within a few min, to avoid overfeeding.

Can Betta Fish live in unfiltered tanks?

Yes, Betta fish can live in unfiltered tanks, but It is recommended to have a gentle filter in the Betta fish tank to maintain water circulation and remove debris. Filters help to keep the water clean and provide a healthier environment for the fish.

Unfiltered tanks require less equipment and maintenance. Some people prefer a minimalist approach to fishkeeping and may opt for an unfiltered tank to avoid the additional set-up and maintenance that comes with a filter.

Some people choose to keep Betta fish in unfiltered tanks for various reasons, The following are-

  • Filters can create water movement and noise, which may not be desirable for those who prefer a calm and serene aquarium environment.
  • Filters can be an added expense, especially if you're on a tight budget. Opting for an unfiltered tank can be a more economical choice initially. However, it's important to consider the long-term costs of potential health issues and the need for more frequent water changes to maintain water quality.

The following are problems faced by Betta fish when kept unfiltered:-

  • Betta fish kept in the unfiltered tank may face several problems due to the lack of filtration. Poor water quality, without a filter, waste products such as uneaten food and fish waste can accumulate in the tank.
  • In an unfiltered tank, there is limited water movement, which reduces oxygen exchange at the surface of the water.
  • Increased disease risk, the presence of waste buildup, and poor water quality in unfiltered tanks create a favorable environment for harmful bacteria, parasites, and fungi.
  • Without filtration, excess nutrients in the water can promote the growth of algae. Algae blooms can reduce water clarity, compete with the fish for oxygen and nutrients, and create an unsightly appearance in the tank.
