Distinguished by their fins, which have elongated, spiked edges resembling a crown. Highly sought after for their unique and impressive appearance. Available in various colors and patterns.
The Crown Tail Betta (or Crowntail) is known for its striking appearance. Its most distinguishing feature is its spiky, comb-like fins that give the tail a "crown" appearance. These rays can extend dramatically beyond the webbing, creating a fringed or serrated look. Crown Tails often come in vibrant colors including reds, blues, turquoise, and multicolored variants. Males display more elaborate fins, while females are more compact.

Carnivorous; prefers high-quality Betta pellets or flakes, supplemented with occasional live or frozen foods.
Crown Tail Bettas are a favorite among aquarists who admire dramatic fin types and elegant swimming. Their bold appearance and expressive personality make them a standout in any freshwater tank. However, their delicate fins make them vulnerable to damage, so tank mates must be chosen carefully. These Bettas are not just showpieces—they’re interactive, intelligent fish that can bring joy to any hobbyist willing to meet their needs. Whether you are breeding for form or just keeping them as pets, Crown Tails are a beautiful testament to Betta variety.

Aggressive (especially males); females less aggressive but still territorial
Feed a balanced diet of Betta pellets rich in protein and omega-3. Supplement with frozen or live food like brine shrimp and bloodworms 2–3 times weekly. Avoid feeding flakes as they can bloat the fish. Provide 1 fasting day per week.
Bubble nest builder; male cares for eggs and fry
To breed Crown Tail Bettas, start with a separate breeding tank (5–10 gallons) with warm water, floating plants, and a sponge filter. Condition both male and female with protein-rich foods for at least a week. The male should be introduced to the breeding tank first and allowed to build a bubble nest. Introduce the female in a see-through container so the male can display and court. Once released, courtship can take hours and involves circling, flaring, and wrapping during spawning. The male places the eggs in the bubble nest and cares for them. Remove the female after spawning. Eggs hatch in 24–36 hours, and fry become free-swimming in 3–5 days. Feed fry with infusoria or baby brine shrimp.

Susceptible to fin rot (especially due to long fins), ich, velvet, swim bladder issues, and constipation. Prevent by maintaining excellent water quality, a proper diet, and using gentle filtration.
Can be aggressive, especially towards other male Betta fish. Best kept alone or in a species-specific setup.
Crown Tail Bettas are highly expressive and reactive to their environment. Males are especially territorial and will flare, chase, or even attack tank mates if they feel threatened. These Bettas are intelligent and can be taught to follow your finger, swim through hoops, and even recognize their owners. They enjoy interacting with humans and are often seen “begging” for food. Females can live together in groups if the sorority is properly managed. Their flowing fins can make swimming challenging, so strong currents should be avoided. Tank setups should include hiding spaces, plants, and low flow to reduce stress.
The Crown Tail Betta is a unique variety of Betta splendens, first selectively bred in Indonesia. Its name comes from its distinct fin structure: long, pointed rays that extend beyond the webbing, giving the tail a jagged, spiked appearance resembling a crown. These Bettas are captivating not only for their looks but also for their engaging behavior. They are known to respond to movement, recognize their owners, and display intelligence uncommon in small fish. Because of their long fins, Crown Tails require calm waters and a tank free of sharp decorations to avoid tearing. While stunning, their beauty comes with the price of needing special care to keep fins healthy. For aquarists looking for a show-stopping centerpiece fish with personality, the Crown Tail Betta is a bold and elegant choice.
