Betta Profile: Halfmoon
![]() |
In the Halfmoon tail type, when fully flared, the caudal should be a full 180-degree half-circle. This is due to an increased amount of ray branching. If the tail is larger than 180 degrees, it is known as “Over Halfmoon”. These tails are symmetrical and very heavy.

This is the type of fish I got at the pet store. Only the lady who worked there said they were called Delta Tails, not a halfmoon betta.
