Here are a few facts on the double tail betta fish that might interest you:
The expression “Double Tail” is often referred to as “DT”. (Useful fact if you are looking up information on-line).
As the name suggests, and as you can see by the picture above, the Double Tail betta has a caudal fin that splits into two equal lobes rather than one.
The DT trait can be found in a wide variety of bettas, however the most popular mixing is done with Plakats, Halfmoons, and even Crowntails. Here’s a quick glimpse of each one to show you the difference:
Double Tail Plakat
Double Tail Halfmoon
If you can get the halfmoon double tail to flare, you will notice that their tails almost make a complete circle.
The Double Tail has over twice the amount of rays in its dorsal fin as a regular single-tailed betta, which has the effect of having a dorsal fin that is also twice as large.
They tend to have a slightly shorter body than other bettas and unfortunately, these little fellas are susceptible to Swim Bladder problems.
For “show” purposes, the perfect double tail betta fish is one that is symmetrical and has two equal tail lobes.
