Delta Tail

A delta tail betta is a fancy form of the Siamese fighting fish, Betta splendens, named for its caudal fin shape. When flared, the tail forms a broad triangle with relatively straight upper and lower edges, wider than many traditional veil or round tails but short of the semicircle expected in a halfmoon. The label can occur alongside many color descriptions, so a black delta tail, butterfly delta tail, koi delta tail, or copper delta tail is still primarily being described by tail shape.

Delta tail bettas are popular display fish because they have dramatic finnage without always carrying the very heavy tail spread of show halfmoons. They still need the standard betta requirements: tropical water, a cycled tank, places to rest near the surface, and housing that prevents fights between adult males. Gentle filtration matters, since a fish forced to battle current may clamp its fins or spend most of its time hiding. When choosing breeding stock, experienced keepers avoid fish with weak peduncles, curled rays, or torn fins, and they do not assume that two attractive adults will produce uniform delta offspring.
