my betta violates natural law

[f250fisherman]

It's a male. He should flare at a female or another male.

Whats a Delta? A delta is a caudal spread less than 165 degrees. Phil Lafferty describes spreads as 180=HM...180 with the edges or corners bending towards the caudal(not the body) as Super Delta...and 165-179 = HMx
