Male Crown Tail Betta - Betta splendens
Scientific Name: Betta splendens
Common Name: Crown Tail Betta, Siamese Fighting Fish
Family: Osphronemidae
Origin: Southeast Asia (specifically the Mekong basin in Thailand, Cambodia, and Vietnam); the distinct "crown tail" variation was selectively bred by enthusiasts in Indonesia in the late 1990s
Size: Up to 2.5 to 3 inches (6.5-7.5 cm)
Lifespan: 3-5 years
Diet: Carnivorous; they require a protein-rich diet consisting of high-quality betta pellets, supplemented with live or frozen foods such as bloodworms, brine shrimp, and daphnia
Temperament: Highly territorial and aggressive, particularly toward other males of their species or fish with similar flowing fins
Water Parameters: Temperature: 78-82°F (25-28°C) pH: 6.5-7.5 Hardness: 5-20 dGH
Tank Size: Minimum 5 gallons (a gentle filter is necessary to protect their delicate, elaborate fins from strong currents)
Compatibility: Best kept as a solitary centerpiece fish; in larger setups, they can coexist with peaceful, short-finned bottom dwellers like corydoras or snails, but one must strictly avoid fin-nippers, other labyrinth fish, or brightly colored tank mates that might trigger their aggressive instincts
