Betta Imbellis (Peaceful Betta): Complete Care Guides, Tank Mates, FAQs

Dive into the captivating world of the Betta Imbellis, also known as the Peaceful Betta or Crescent Betta. This species of gourami, native to Southeast Asia, is a marvel to behold and a joy to care for. The Betta Imbellis is a truly exceptional choice to enhance the beauty of your aquarium. This incredible fish belongs to the domain Eukaryota, kingdom Animalia, phylum Chordata, class Actinopterygii, order Anabantiformes, family Osphronemidae, and genus Betta.

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.

Ideal Tank Mates

When considering tank mates for your Betta Imbellis, it’s important to choose species that are peaceful and of similar size. The Betta Imbellis is generally a peaceful fish, but males can become aggressive during breeding season. Therefore, it’s best to avoid any species that are known to be fin nippers or overly aggressive. Here are ten ideal tank mates for your Betta Imbellis:

Can Betta Imbellis Live with Other Betta Species?

While Betta Imbellis is generally peaceful, it’s not recommended to house them with other Betta species, especially Betta Splendens (Siamese Fighting Fish). The aggressive nature of Betta Splendens can lead to conflicts and stress for the Betta Imbellis.

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?

Betta Imbellis are tropical fish and prefer warm water. The ideal water temperature for Betta Imbellis is between 24-30°C (75-86°F). They can tolerate slight fluctuations in temperature, but prolonged exposure to cold water can lead to health problems.

Do Betta Imbellis Need a Filter in Their Tank?

While Betta Imbellis can survive without a filter due to their labyrinth organ that allows them to breathe air, it’s still recommended to have a filter in their tank. A filter helps maintain clean water by removing waste and harmful chemicals, which contributes to the overall health and well-being of your Betta Imbellis.

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. Stress can be caused by various factors such as poor water quality, inappropriate tank mates, illness, or a lack of hiding spots. If you notice these signs, it’s important to identify and address the cause of the stress to ensure the health of your Betta Imbellis.

Can Betta Imbellis Live Alone?

Yes, Betta Imbellis can live alone. In fact, they can sometimes prefer it, especially during breeding season when males can become territorial. However, they can also live peacefully with suitable tank mates as discussed earlier.

How Often Should I Change the Water in My Betta Imbellis Tank?

It’s recommended to change 10-20% of the water in your Betta Imbellis tank every week. This helps maintain the water quality and remove any accumulated waste. However, the frequency may vary depending on the size of your tank, the number of fish, and whether you have a filter or not.

Can Betta Imbellis Recognize Their Owners?

While it’s hard to say for certain, many Betta Imbellis owners report that their fish seem to recognize them. They may swim towards the glass when their owner approaches or show excitement during feeding times. However, this is more likely a response to the anticipation of food rather than recognition.

What Should I Do If My Betta Imbellis Is Sick?

If your Betta Imbellis is showing signs of illness such as loss of color, decreased activity, refusal to eat, or unusual swimming behavior, it’s important to take action. First, check the water parameters to ensure they are within the suitable range for Betta Imbellis. If the water conditions are fine, consider consulting with a vet or an aquarium professional. Some illnesses can be treated with over-the-counter medications, but others may require professional help.

Can I Keep More Than One Betta Imbellis in the Same Tank?

Yes, you can keep more than one Betta Imbellis in the same tank, provided the tank is large enough to prevent territorial disputes. Unlike Betta Splendens, Betta Imbellis are generally peaceful and can live together, especially outside the breeding season. However, it’s still important to monitor their behavior to ensure there are no conflicts.

How Can I Make My Betta Imbellis Happy?

To keep your Betta Imbellis happy, provide them with a suitable environment that includes plenty of hiding spots and room to swim. Maintain clean water with the right parameters and feed them a varied diet. Also, try to minimize stress by avoiding sudden changes in water conditions or introducing aggressive tank mates. A happy Betta Imbellis will be active, show vibrant colors, and have a good appetite.
