K.G.BETTAS

Extended red DR CT

Here the tail rays extend beyond the tail edge, producing a crown-like appearance (sometimes referred to as “Combtail”). How much the rays may extend depends on the genetic makeup of the fish. The crowntail trait can be found in bettas of any tail type and shape. For instance it can be seen in VT, D, SD, HM (CTHM = half-sun) and DT. The crowntail gene is recessive (or actually intermediar), but singletail carriers most of the time already show more or less extended rays beyond the tail edge.

Crowntail genetics

A normal singletail betta is represented by: ctct
A crowntail betta is homozygous for the crowntail gene (CT) and is represented by: CTCT

A singletail betta which is carrier for the crowntail gene is then represented by: CTct

- When a crowntail male (CTCT) is crossed with a single tail female (ctct), their offspring will be 100% singletail and carrier for the crowntail gene(CTct).
- When a singletail crowntail carrier male (CTct) is crossed with a single tail crowntail carrier female (CTct), their offspring will be 25% crowntail (CTCT), 50% singletail and carrier for the crowntail gene (CTct) and 25% singletail (ctct).
- When a crowntail male (CTCT) is crossed with a crowntail female (CTCT), their offspring will be 100% crowntail (CTCT).
