Double Tail Betta
Betta splendens 'Double Tail'
Family: Osphronemidae
The Double Tail Betta carries a genetic mutation that splits the caudal fin into two distinct lobes, giving the appearance of two separate tails. This same mutation often also shortens the body and broadens the dorsal fin significantly. Double tails tend to be weaker swimmers than single-tail varieties and are more prone to swim bladder issues; careful feeding with high-quality food helps mitigate this.
