🐟 Rosetail Betta Fish (Betta splendens)
Freshwater Betta • Solitary Species • Flowing Rosette Tail • Beginner–Intermediate
📋 The Rosetail Betta (Betta splendens) is a highly ornamental variety bred for its extreme branching fins and expanded caudal spread, creating a lush rosette-style tail.
The heavy branching and wide tail create a flowing, graceful swimming style, making each movement look like a blooming flower in the water.
Because of the extra finnage, Rosetail Bettas are best kept as solitary fish in calm aquariums with gentle flow and carefully chosen tank décor to protect their fins.
Visually stunning and expressive, the Rosetail Betta is ideal for aquarists who want a true showpiece betta, but it is slightly more delicate than short-finned varieties.
