Halfmoon dumbo betta fish are the most common variety of fish in the pet industry. This makes it all the more important to be prepared to take care of them properly and to know what you’re getting into before you make the decision to bring one home.

The dumbo halfmoon betta fish are beautiful, but they do have specific care requirements that other betta fish do not. They are popular in the world of tropical fishkeeping, thanks to their unique and attractive coloration.

The fish are some of the most beautiful fish around, but they also come with a few extra requirements that must be met in order to thrive.

This guide will walk you through everything you need to know about how to take care of your halfmoon dumbo betta fish, including diet, tank maintenance, and even how to troubleshoot some problems that may arise over time!

Origin and descriptions

Halfmoon dumbo betta fish originated in Thailand. Although there are many hybrid betta fish varieties, the halfmoon is one of my favorites. It has a beautiful skirt that makes it stand out from other types of bettas.

You may find some success with breeding them if you take your time and do your research.  The male halfmoon will develop more color than his female counterpart; however, both genders will still have nice coloration. In general, males also have longer fins than females. The first step to taking care of your new pet is choosing an appropriate tank for him or her.

When choosing a tank for your new friend, make sure it has plenty of space for swimming around. Bettas are known for their speed and agility in water so you need to give them room to move around!

Species profile

Halfmoon dumbo betta

They have a relatively short lifespan compared to other types of fish, with an average life span ranging from one to four years in captivity. Their coloring is often less vibrant than that of other types of bettas due to a lack of pigmentation in certain areas; however, they make up for it with their unique tail shape and personality traits.

Scientific name

The scientific name of the dumbo halfmoon betta fish is Betta splendens.


Their natural habitat is in slow-moving waters of ponds, swamps, and rice paddies. These fish are very sensitive to water quality and need clean water to thrive.

Dumbo halfmoons can be found in ponds and rivers of South Asia, Malaysia, Indonesia, Sumatra, Java, and Thailand. Their more docile cousins are used for aquaculture in China. The fish has experienced a decline in numbers due to pollution and poaching.

If you’re keeping a Dumbo halfmoon betta in your aquarium or garden pond, be sure to check local laws on exotic pets. Some countries require exotic pets to be neutered or held captive with permits.

Halfmoon dumbo betta fish size

Halfmoon dumbo betta fish vary in size depending on their environment. Their sizes range from 2-3 inches (5-8 cm) in length.

Tank size

Halfmoon dumbo betta fish prefer a tank of at least 5 gallons, though 10 gallons are ideal. Anything smaller may be too crowded for your fish and anything larger isn’t going to be good for its long-term health.

Tank requirements

Halfmoon dumbo betta fish should live in a 10-gallon or larger tank with filtration and a heater. They like to have lots of plants, caves, and other hiding places to help them feel secure. Because they are sensitive to changes in water quality, it’s important that you perform regular water changes (once every two weeks) using a good filter.

You can also add aquarium salt at 1 teaspoon per gallon to improve their health. You will need to feed your halfmoon betta fish several times a day because they are very active and eat small amounts frequently. For optimal health, feed your halfmoon betta fish high-quality flake food or pellets for carnivores along with freeze-dried bloodworms, tubifex worms, and brine shrimp for variety. They also enjoy snails as an occasional treat!

Tank mates

Because of their potential to be aggressive, halfmoons shouldn’t be kept with other betta fish or small aquarium fish. They are compatible with larger aquarium fish such as goldfish, guppies and angelfish.

Some owners also successfully keep halfmoons with larger, non-aggressive species such as tiger barbs, silver dollars, and blood parrots. Of course, it’s always important to do your research before choosing tank mates for your betta.

If you’re interested in breeding these fish, it’s important to understand how they reproduce. Halfmoon dumbo betta fish breed by spawning on flat surfaces like leaves or rocks. Male halfmoon dumbo bettas build nests from bubbles produced by their mouths, which they then defend from other males during mating season.

When a female enters his territory, he will try to entice her into his nest by showing off his colors and flaring his fins. Once she enters and lays eggs, he will release sperm into her water column.

She can lay between 20 and 100 eggs and the male guard them until they hatch. The fry will be free-swimming within three days and should be fed infusoria initially. After two weeks, they should be eating baby brine shrimp.

At four weeks old, they should be able to eat adult foods like frozen brine shrimp or bloodworms. It’s very important not to overcrowd your fry tanks; having too many small fish in a tank makes it difficult for them to find food and increases their risk of disease.

Are they peaceful or aggressive?

Halfmoon dumbo betta can be territorial and aggressive toward other species of fish. Because they are so aggressive, it’s important to select a healthy individual when purchasing them.

It’s best not to mix different species unless you have a large tank with plenty of space for each individual fish. If keeping multiple halfmoons together isn’t an option, consider purchasing two smaller tanks instead of one large tank so that each betta has his own space.

The halfmoon dumbo betta has very different needs to a standard or plakat betta, so it’s important to note that you can’t keep a halfmoon dumbo with other types of betta fish. They are also prone to swim bladder problems, so your aquarium must be as bare and clean as possible – no hiding places or decorations!

In terms of water conditions, these fish prefer soft acidic water. You should maintain a pH between 6.5-7.0; the temperature should be kept at around 23-27 degrees Celsius.

Halfmoon dumbo betta diet

In terms of diet, feed your betta live foods such as mosquito larvae and brine shrimp; frozen foods such as bloodworms are also recommended. A varied diet is essential for a healthy betta fish.

It’s also worth noting that many aquarists recommend feeding them every day rather than every second day because they have an increased metabolism compared to normal bettas.

If you want your halfmoon dumbo betta to show its beautiful colors, then make sure you do not overfeed it: fat fish tend not to show their fins! They will still enjoy eating, however, so don’t stop feeding just because they aren’t showing off!

Parasites and diseases

Halfmoon dumbo betta fish are most vulnerable to parasites and diseases in their first few weeks of life. Because these fish are especially susceptible, it’s important that you quarantine any new arrivals for 30 days to be sure they don’t have any undetected parasites or diseases.

To prevent infection, always use separate containers for sick fish—never treat healthy fish with medications meant for sick fish, as there is a risk of cross-contamination and improper treatment. Also, never release water from an infected tank into another tank.

If you notice your betta fish has white spots on its body or fins, which can appear as early as three weeks after birth, isolate it immediately. White spots are caused by ich (ick), a parasite that will eventually kill your betta if left untreated. The good news is that ich is easy to treat; simply purchase medication from your local pet store and follow instructions carefully.
