Been growing this flower horn out since it was about 1 inch. Probably about 3.5 inches now and tried to vent it today. Hoping it’s a female but can’t really tell? Anyone have any idea?
Using the oo = M oO = F method I would guess male, since the vent and the anus are approximately the same size. But in this case, the fish is very overweight and it’s bulging belly could change the shape and appearance of the vent.
