question for ya. i always read that most of the time oo is male and oO is female but everytime i try to vent my fish i can see oo on some but the others are o and then a oval behind it. would the oval be the same as the larger O your talking about. cause if thats the case most of my fish are female. Im still trying to get this venting down so im 100 percent sure on sexing my fish. thx
