Can anyone tell me at what size I can determine the sex of Oscars? I assume this will be done through the size of the vent? Thank you for any info on this.
Well I have already used the vent ID method to an oscar approx 5-6 inches and could see the difference. Just wasnt sure how small you can really see with the naked eye.
yea i agree it is possible for a 5in oscar i dont know how small they can get. you may want to research venting there are very good websites to help you out with this.
