Betta Unimaculata is a freshwater fish betta species living in murky waters and has developed a long dorsal fin spine. Betta Unimaculata is a carnivorous fish that eat both plant and animal matter for sustenance.


The belly of this betta unimaculata is covered with small, hard, black, and white spots known as anal fins. These allow the betta fish to detect its prey through sound, sight, smell, and motion. The anal fins are also used to help the betta navigate its environment.

We will cover everything you need to know about caring for your Betta Unimaculata, from setting up its tank to feeding it the appropriate food.

Betta Unimaculata Tank Requirements

Size Of Betta Fish Tank

The minimum size tank for a Betta Unimaculata is 15 gallons. It should have plenty of space for swimming for your fish but not large enough for a goldfish to make it feel threatened.

The only way to get the most out of your betta unimaculata is to keep it in a large aquarium with multiple levels that provide lots of hiding places while providing plenty of open swimming room.

This will allow your fish to enjoy its natural environment while having adequate space to swim and feed.

Although Betta Unimaculata is a tropical fish that lives in freshwater, it can be easily adapted to most aquariums because of its high temperature and pH levels tolerance. It is essential to keep the water at a constant temperature of 74 F (23 C) and keep the pH level between 6.6 and 7.8.


Light availability can be a major problem when placed in an aquarium with Betta Unimaculata. The Betta dimly illuminates its surroundings using organs called photophores on its body, anal fin, dorsal fin, and tail fin.These serve as their main source of light.

The total amount of dim lighting available to the Howong betta fish is governed by the betta Unimaculata size and the size of the aquarium and the cover of plants. These organs can become useless in an aquarium with no cover over them.

Lighting requirements are more critical for temperature control and are directly related to these bacteria. Water parameters need to be stable for your betta Unimaculata for its microbial balance to be maintained appropriately.

Like most tropical fish, betta unimaculata complex needs live floating plants as hiding places and a way to keep mosquitoes away from its tank. The tank should also have plenty of places to climb on the walls, caves to hide, and dense vegetation.


The substrate of the tank should be a sandy or slightly sandy mixture. It should have a high fiber content like gravel. A peat-based substrate can lead to the formation of fungus in your aquarium and can also foster anaerobic bacterial growth that causes harmful gas production and fish death.

Other good options are sand, river sand, potting soil, or wood shavings. Sand gives the betta Unimaculata a better place to hide, while wood is used as a substrate because it is easy to clean.

Water Quality

The water used in your tank must be acidic and soft so that nothing in the tank dies. It’s essential not to use tap water if you can avoid it. Hard or alkaline water can lead to several problems, like fish death and bacterial imbalance.

Water needs to be kept at a constant temperature of 72-78 degrees F (22-25 degrees C). You could use something like an aquarium thermometer to tell you what temperature your fish should be.

Feeding Your Betta Unimaculata

Betta Unimaculata feeds on small particles of decaying vegetation. These particles include micro-plants, algae, and even decaying food. The natural diet of this fish can make it difficult to feed it as its teeth are worn down from constant grazing.

However, proper Betta Unimaculata care and a healthy diet can keep you from stressing out while feeding this Howong betta and other species.

Your betta Unimaculata can be fed with various foods: live, frozen and freeze-dried foods. Live food is ideal if you have the time to take care of it. It can include mosquito larvae, bloodworms, brine shrimp, and dried leaf litter.

These are easy to find at your local pet store, and they are very nutritious for fish. The frozen foods Betta Unimaculata enjoy include krill, daphnia, and glass worms. Freeze-dried foods include tubifex worms, bloodworms, and brine shrimp; however, these are often hard to find and expensive.

Betta Unimaculata is a carnivorous fish that does very well in an aquarium, especially if you have a large tank. The bigger the tank, the easier it will be for you to take care of your betta Ocellata.

Breeding Your Unimaculata Betta Species

Most male Bettas are territorial and aggressive towards other male Bettas. They will not tolerate another male in their territory, so they can only be kept with female Howong betta Unimaculata.

Bettas are best suited to rather peaceful fish community tanks rather than breeding tanks because other fishes may harm the eggs or small fish. They should also be kept away from large predators such as goldfish and cichlids because they can eat them.

A Betta Unimaculata tank should have a fast-moving substrate so that the eggs can be safely buried in the sand and out of reach of potential predators.

Breeding Betta Unimaculata bettas is extremely difficult.

The fish are small, have to be kept alone, and do not usually form pairs. There are at least two males for every female, as this Howong betta species can become aggressive if kept with others.

Also, some females may be able to mate with other females without showing any signs of pregnancy. As with many Howong betta groups, only one male out of ten or twelve females is willing to breed.

There are two main methods of breeding this species: livebearing and egg-laying. Livebearing is the most difficult to carry out as you may have to separate the male from the female for long periods. Egg-laying is much easier, as males will not harass the females or become aggressive for a very long time.

Just remove any other fish that may be a threat and pair them in an aquarium among one another or with a single female. Females may lay up to 300 eggs at once, so a single male can incubate thousands of eggs at once.

Eggs are usually laid on a flat rock but can also be laid under plants or plants in which they can hide from predators. This is why it is important to have floating plants within the tank to keep your females and their offspring safe.

The female will guard the eggs by fanning them with her fins or body until they hatch into extremely small fry. The fry can eat very small micro-organisms but must still be fed with particular food particles.

Benefit Of Forest Streams In Betta Unimaculata Aquarium

The tropical forest streams in betta unimaculata aquarium have various benefits.

The first and foremost is that it provides an environment that is different from most Howong betta aquaria.

For many years, the freshwater fish hobby has emphasized maintaining a tank that replicates water directly from the same source. By using tropical flowing streams in a betta unimaculata aquarium, you can see how different the two environments are.

Bettas thrive in this environment because it provides a filtered and clean form of water which they prefer to live with. With the addition of plants and long-finned fish, you can create an environment with a deluge of betta unimaculata.

A tropical forest stream is also known to offer an abundance of bacteria, which is beneficial for converting nitrates, leading to problems in wild bettas water. We recommend using pitcher plants such as Sagittaria and Java moss to ensure that the water remains clean and healthy.

Betta Unimaculata Behavior

Wild bettas are territorial fish that constantly try to find something to fight. They are very active and love to splash water at everything they see.The best way to keep a betta unimaculata calm is by giving it a well-planted tank with access to places of refuge.

Male betta fish will go through a courtship ritual to attract their chosen mate. The female betta is generally more colorful and with more curves, while the male betta fish is smaller, thinner, and may have longer fins.

It is important to note that males can only breed once a week, so they will fight if you have more than one of them.

Female betta fish can live with other females and possess a broader head shape, but males should be kept alone or in tanks divided by a partition.

Sexual Dimorphism

The breeding adult male and female betta unimaculata are pretty different in appearance.

The adult female is much more colorful than the male, with a more pronounced belly and visible sexual characteristics.

The male has a shorter dorsal fin spine, slightly broader head, and less distinct and vibrant coloration.

Male Betta Unimaculata has a brighter color pattern than females, with an orange belly and fins, typically ranging from bright orange to bright red with various black or white spots located along the sides of their dorsal fins. The anal fin also has black spots on them. Females are often deep pink to red in coloration.

Can You Put A Male Betta Unimaculata In A Community Tank?

It is not advised to put a male betta into a community tank as a rule.

If your choice is to keep the betta with other fish, you would have to be very careful when selecting other tank mates and only add in the ones you know are compatible.

There Are 2 Types Of Males

Breeding (usually they do not want to pair up with another male) and non-breeders (generally very aggressive and do not calm down once paired). The non-breeder males are more aggressive, so it is better to have only one if you put them together.

Howong Betta is a rather peaceful fish, of which only males are aggressive to each other. They tend to live in sections of forest streams with clear water over sandstone rocks and no algal growth.


The Betta Unimaculata is very beautiful and easy to care for fish. The male betta ocellata will live in this space and become quite territorial when he senses another male betta unimaculata or other fish in the tank. It’s important not to add any plants because this could cause harm to your Howong betta Unimaculata.

The Betta Unimaculata has long been considered the pinnacle of beauty among the many species of Betta. Its undeniable charm has garnered cult-like admiration from owners worldwide who enjoy their company in a wide variety of biotopes and containers.
