In the case of this betta, the anal and dorsal fins are a bit long for a female. On short finned male bettas, the tail is short but the anal and dorsal fins are still usually much longer than those of similarly sized females. Also, females will have an "egg spot" on their belly. Males will have a larger "beard" when flaring and are more likely to flare for a mirror.
Ahh I see. This one is amazing in color. Will he change colors?
