Is A Butterfly Betta A Color Pattern Or Fin Type?

[guppy2002]

I just got a beautiful betty labeled "butterfly betta". What exactly does that mean?

I believe that a butterfly betta is a betta whose fins all are one color except for the edges which are also one different color. The edges should be fairly even and should be the same on the caudal, dorsal, and anal fins. The edge is usually white.

As atti says it's a colour type - the even stripe.
Fin types refer to the shapes of the fins rather than the colour.
This is a good place to see all the various colour and fin types:

Butterfly is a color pattern that mainly turns up in marble lines.  Butterfly can show up in any tail type and any color, male or female.  The fins have to show at least two of the same colors on all 3 fins, the more even the color split (50/50 being perfect) the better.
