The Betta Imbellis is not considered a rare species. It’s listed as “Least Concern” by the IUCN Red List. However, it faces threats from pollution and hybridization with released domesticated bettas (Siamese fighting fish) and other bettas in the B. splendens complex.
Although the specific variants of the Betta Imbellis are not widely recognized, bettas in general are famous for their extensive range of colors and fin types as a result of selective breeding. The males of the Betta Imbellis species are particularly striking, boasting blue hues in their brownish bodies.
The natural habitat of the Betta Imbellis spans Southern Thailand, Malaysia, and Indonesia, and the species has also been introduced to Singapore. They prefer sluggish bodies of water, such as rice paddies, swamps, streams, and ponds, with substrates composed of leaf litter and mud. Despite their peaceful moniker, males of the species may engage in fights, especially during breeding season. In their natural habitat, these creatures rely on a combination of land and water-dwelling invertebrates for sustenance. However, when they are kept in captivity, their diet is carefully curated to include live or frozen delicacies such as Daphnia, Artemia, or bloodworms.
The Betta Imbellis grows to a maximum standard length of 6 cm (2.4 in), making it a compact yet captivating addition to any aquarium. This species is equipped with a pair of suprabranchial chambers, each housing an air-breathing organ known as the labyrinth organ. The Betta Imbellis is able to thrive in extreme conditions thanks to its complex bony structure, which is lined with thin, highly vascularized respiratory epithelium. This unique adaptation allows the species to efficiently extract oxygen from the air.
One fun fact about the Betta Imbellis is its unique breeding behavior. After mating, the male catches the falling eggs and places them in his bubble nest. In 1–2 days, the eggs hatch and continue to absorb their yolk sack for 2 more days. After that, the fry become free swimming, with the male caring for them until this point.
The Betta Imbellis was first described by Werner Ladiges in 1975 and has since become a popular choice in the aquarium trade. Its captivating colors, unique adaptations, and intriguing behavior make it a favorite among aquarists worldwide.

How Often Should I Feed My Betta Imbellis?
Betta Imbellis should be fed once or twice a day. It’s important not to overfeed them as this can lead to health problems. A good rule of thumb is to only feed them what they can consume in 2-3 minutes.
What Are the Signs of a Healthy Betta Imbellis?
A healthy Betta Imbellis will have clear eyes, vibrant colors, and an active demeanor. They should be eager to eat and show interest in their environment. If you notice any changes in behavior, loss of color, or refusal to eat, it may be a sign of illness.
Can Betta Imbellis Live in Cold Water?

Do Betta Imbellis Need a Filter in Their Tank?

Can Betta Imbellis Jump Out of the Tank?
Like many other fish species, Betta Imbellis are capable of jumping. It’s advisable to have a lid on your aquarium to prevent any potential escape attempts. However, ensure the lid allows for some air exchange as Betta Imbellis need access to the water’s surface to breathe air.
What Should I Do If My Betta Imbellis Is Not Eating?
If your Betta Imbellis is refusing to eat, it could be due to several reasons such as stress, illness, or unsuitable water conditions. Try changing their diet or adjusting the water parameters. If the problem persists, it’s best to consult with a vet or an aquarium professional.
How Can I Tell If My Betta Imbellis Is Stressed?
Signs of stress in Betta Imbellis can include loss of color, decreased activity, hiding, refusal to eat, and rapid breathing.
