Guide: Keeping Betta Fish


The Betta fish, or Betta Splendens, is originally native to Thailand, but has gained popularity as a domestically raised species for worldwide distribution as a popular aquarium fish. The original habitat of the Betta fish is a slow moving shallow puddle among the rice fields where they live their lives in small stagnant pools.


Why they make great pets and great beginner fish:

Bettas make great pets and are very popular due to their vibrant jewel-tone coloration. Due to the fact that the wild Betta fish do not require large expansive tanks or quickly moving water, the Betta fish is a great choice for the first time fish keeper. They do prefer to live in solitude and do not get along with other Betta fish, however other peaceful fish can make very nice tank mates for the Betta fish in a filtered tank. Bettas can live in any aquatic environment from a small lowly filtered bowl, to a large filtered aquarium.


Water parameters and care:

Ammonia: low to 0 ppm

Nitrite: low to 0 ppm

Nitrate: under 20ppm

pH: 7.0

GH: 5-20 dH or 70-300 GH ppm

Temperature: 25.5° and 26.5 C


  • We recommend the use of Seachem Betta Basics to remove chlorine and chloramine from tap water and to set pH to a neutral 7.0 which is ideal for Betta fish.
  • Alternate product choices: Seachem Prime or Seachem Neutral Regulator


Betta fish typically have a high metabolism and require a diet rich in protein. As with any fish, vegetable matter is also important as well. Seachem NutriDiet Betta will provide a wide range of nutrient benefits, as it is rich in nutrient sources such as Alfalfa, Squid, Fish Meal, and Chlorella Algae. Bettas prefer to eat several small meals versus one large meal, so feeding a few pellets a few times a day is recommended.



Water changes can be done as necessary and we recommend that you change at least 10-20% weekly in small betta environments to keep the fish healthy and tank environment free of organic build-up. In addition, Seachem Stability is a great choice for adding a boost to bio-filtration after water changes as well as between water changes.
