Male anal fin is not transparent like female and anal fin of male at the base is thick.Isn’t it’s anal fin smaller? Idk
In general, the anal fin for male bichirs is broad at the base, with almost no gap between the anal fin to the tail fin. Additionally, it tapers out into a slight wave shape. Female anal fins typically have a visible gap between the anal fin and tail fin. The anal fin is also more rectangular; usually, the anal fin is approximately the same width at the base and at the end of the fin.Isn’t it’s anal fin smaller? Idk
