Care, breeding and tankmates

Fish profile

Temperament

Aggressive

Males are famously territorial and highly aggressive toward other males of their own species or any fish with similar long fins and bright colors. They will flare their opercula to display dominance and will fight to the death if confined together. Females are generally less aggressive but can still establish a strict pecking order. Despite their intraspecific aggression, they are often peaceful toward completely different species that do not resemble them.

Diet

Carnivore

As obligate carnivores, Dragon Scale Bettas require a diet rich in high-quality protein. Their primary nutrition should come from specialized betta pellets or flakes formulated with marine proteins. This should be supplemented with live or frozen foods such as bloodworms, brine shrimp, and daphnia. If the fish develops diamond eye, sinking foods or feeding rings can help them locate their meals by smell and routine.

Life expectancy

2-5 years

The average lifespan of a Dragon Scale Betta in captivity is between 2 to 5 years under optimal care conditions. However, due to selective breeding for their thick metallic scales, they are prone to a condition called diamond eye, where scales grow over their eyes. This visual impairment does not shorten their life directly but requires adjusted feeding care. Providing high-quality nutrition and clean water is key to maximizing their lifespan.

Sex ratio

Solitary

Dragon Scale Bettas are best kept individually, as they do not require or tolerate tank mates of their own species in typical setups. Keeping multiple males together will result in aggressive territorial fights that are often fatal. Females can sometimes be kept in groups, known as sororities, but this requires a large, heavily planted aquarium and significant experience. For average hobbyists, a single specimen per tank is the safest and most stress-free stocking method.

Feeding frequency

Twice daily

It is recommended to feed Dragon Scale Bettas once or twice a day in small portions. Only offer what they can consume within one to two minutes to prevent overeating and water contamination. Bettas are prone to bloating and constipation, so fasting them one day a week is a highly beneficial practice. Adjust the feeding amount based on the fish's activity levels and physical condition.

Bioload

Low

The biological load of a single Dragon Scale Betta is relatively low, making them suitable for smaller, filtered aquariums of at least 5 gallons. However, they are sensitive to accumulating ammonia, nitrites, and nitrates, which requires consistent water changes. A gentle filtration system is crucial to keep the water clean without creating a strong current that could exhaust the fish. Regular maintenance of the filter media ensures that the water quality remains pristine and stable.

Flow

Stagnant

This species prefers calm, slow-moving, or stagnant water, reflecting their natural wild habitats in rice paddies and marshes. Strong water currents will quickly exhaust the fish, especially varieties with long, heavy fins, leading to stress and immune system suppression. A gentle sponge filter or an adjustable filter set to the lowest flow is ideal. You can also use tall plants and decor to break up any remaining water currents.

Jump risk

Yes

Dragon Scale Bettas are excellent jumpers and can easily leap out of an open aquarium. They are often startled by sudden movements or lighting changes, which can trigger an escape jump. A tight-fitting lid or cover slides are absolutely essential to prevent fatal accidents. Additionally, keeping the water level slightly below the rim provides an extra safety margin.

Reproduction

Oviparous

Breeding this species is a complex process that involves the male building a bubblenest at the water's surface. The male coaxes the female to spawn, fertilizes the eggs as they are released, and carefully places them into the bubbles. After spawning, the female must be removed immediately to prevent the male from attacking her out of parental protectiveness. The male will guard the nest until the fry are free-swimming, at which point he also must be removed.

Compatibility & tankmates

Solitary

Males must be kept solitary or with carefully selected tank mates in a community tank of at least 15 gallons. Suitable companions include peaceful bottom-dwellers like Corydoras catfishes and small, fast-swimming, short-finned schooling fish like rasboras. Avoid housing them with fin-nippers, highly active species, or fish with bright colors and long fins that might trigger aggression. Females can sometimes cohabitate in large, heavily decorated tanks, but individual personalities vary significantly.

Tank level

Top/Middle

This species primarily inhabits the middle to top levels of the aquarium, where they can easily access the surface. As labyrinth fish, they possess a specialized organ that allows them to breathe atmospheric air directly. Providing floating plants or resting ledges near the surface will give them comfortable spots to rest and breathe. They will occasionally explore the bottom of the tank, but their main activity is concentrated in the upper water column.
