I don't think anyone was implying that he is a moron. He asked, and people are giving their opinions. The key feature to look for if one is unsure of a betta being a double tail is, as Auratus mentioned, the dorsal fin. Double tails have dorsal fins that are significantly wider then all other tail types.TechnicolourBetta said:Either way it's a beautiful fish and you guys really shouldnt just assume that this person is wrong about it, Just because he's curious as to what the tail type is or what you think, doesnt mean he's a moron like you are treating him.
