There was another one just like it but it was a different color but still beautiful.Okay, so obviously this fish is a female, the finnage is is looser and smaller than a male, from what i can tell on the pictures it looks like a plakat, i can definitely not tell for sure, but i have quite extensive knowledge on betta fish and i can tell you for sure, you got a beautiful fish right there.
