Five Quick Betta Fish Facts

Looking for quick betta fish facts, then you have come to the right place. The experts at have compiled an all you need to know top list of the most important facts about rumble fish.

Here is our top five…

  1. The Betta Fish Diet: In the wild, they feed on zooplankton and the larvae of insects, such as flies, crickets, mosquitoes or grasshoppers. Bettas that feed on wide range of foods live longer in the wild. Consequently they have richer colors, and any fin damage heals quicker. In captivity, most commercial betta fish food pellets are a combination of mashed shrimp and fish meal, brine shrimp, bloodworms, and additional vitamins. These fish will also eat live or frozen bloodworms, brine shrimp, or daphnia.
  2. Fighting Fish Colors: In the wild, betta fish only exhibit strong colors when they are agitated. In captivity, rumble fish breeders have been able to make these colors permanent. Thus a wide variety of colors are available such as red, blue, turquoise, orange, yellow, green, cream and even white. The shades of blue, turquoise and green are slightly iridescent, and can appear to change color with different lighting conditions or viewing angles. This is because these colors are not due to pigmentation, but they are created through refraction within a layer of translucent guanine crystals.
  3. Betta Fish Size: Rumble fish usually grow to an overall length of about 2.5 inches. Some bettas reach 3.1 inches in length. In the past ten years, breeders have been able to create "giant bettas" that have grown to 4 inches by manipulating a mutant gene. Look for these fighting giants in some of our slide shows!
  4. Betta Fish Lifespan: Rumble fish live approximately 2–5 years in captivity. It is more than likely though that they will live between 2 to 3 years. It is rare that they exceed 4 years.
  5. Types of Bettas: The most common types of bettas in captivity are the Veil tail, the Crown tail, the Comb tail, the Half-moon, the Plakat, the Double-tail, the Delta tail, the Fantail, the Half sun, and the Rose tail. Complete descriptions of each type of betta can be found on the Betta fish names page.
