Overview: The Crowntail is perhaps the most "aggressive-looking" of all Betta varieties. It is defined by a unique genetic mutation that causes the webbing between the fin rays to be greatly reduced. This results in long, spiky extensions that resemble the points of a crown. To be classified as a true Crowntail, the webbing must be reduced by at least 33% on all fins. They come in every color imaginable, from solid "Royal Blue" to multi-colored "Fancy" patterns.
Origins: This variety was first developed in Indonesia in the late 1990s by a breeder named Achmad Yusuf. It was a revolutionary departure from the soft, rounded fins of the traditional Veiltail and quickly became a global favorite for its "punk rock" aesthetic.
Personality: Crowntails are known for being particularly energetic and feisty. Because their fins have less surface area than a heavy Halfmoon, they are faster and more agile swimmers. They are highly intelligent and very reactive to their surroundings; they will often "flare" their gills and fins at their owners (or their own reflection) in a spirited display of bravado.
Care Level: Easy
Temperament: Highly Territorial (Solitary)
Diet: Carnivore (High-protein pellets, frozen bloodworms, and Mysis shrimp)
Max Size: 6 – 7.5 cm
Family: Osphronemidae
Tank Size: 20 Litres minimum (40 Litres is ideal for stability)
Temperature: 24°C – 28°C
pH: 6.5 – 7.5
Should be kept in groups? No. Males must be kept singly. They will fight other males to the death and should not be housed with other long-finned or colorful species that they might mistake for a rival Betta.
Pro Tip: Because their fin rays are so exposed, they are slightly more prone to "fin rot" if water quality isn't kept pristine. Regular water changes are the best way to keep those "crown points" sharp and healthy!
