Common Fin Types:
* Double Tail: The most common fin type, it has two distinct lobes (like a butterfly) that are roughly the same size.
* Halfmoon: An iconic betta fin type with a wide, circular tail that forms a perfect 180-degree arc.
* Rosetail: Known for its delicate, fringed appearance that resembles a rose. The petals can be long and flowing or short and rounded.
* Delta Tail: A triangular-shaped tail with a wide base and a pointed tip.
* Veiltail: Distinguished by long, flowing fins that drape gracefully behind the betta.
* Spadetail: A shorter, more compact tail that resembles the shape of a spade.
Other Fin Types:
* Crowntail: Characterized by pointy, spiky rays that create a crown-like appearance.
* Super Delta: A highly sought-after type with an extra-wide tail and a sharper point.
* Over-Halfmoon: A type that surpasses the 180-degree arc of a Halfmoon, often exceeding 180 degrees.
Important Considerations:
* Fin Size and Length: Fin size can vary significantly, from short and stubby to long and flowing.
* Fin Shape: The shape of the fins can range from rounded and delicate to sharp and pointed.
* Fin Color and Pattern: Betta fins come in a dazzling array of colors and patterns, adding to their beauty.
Ultimately, the "normal" fin type for a betta fish is whatever type you prefer. Each type has its own unique appeal, and it's up to you to choose the one that best suits your taste.
