Rosetail Betta
Betta splendens 'Rosetail'
Family: Osphronemidae
The Rosetail Betta is an extreme variation of the Halfmoon with excessive branching of fin rays that causes the tail to ruffle and overlap, resembling rose petals. While visually spectacular, the over-developed fins are heavy and fragile, making the fish a weaker swimmer and more susceptible to fin rot, tearing, and spinal curvature. Best kept in very clean, still water and considered a display specimen.
