Pacu sex: how do you determine the sex of pacu fish ?
I am not asking for your opinion whether or not I have a tank big enough to house such a beast. I am asking the difference between a male and a female pacu for breeding purposes. Don't answer this question if your only comment is "It will be obvious when they grow to 3 feet. I'm sure you have a tank big enough for that!"--bullsh!t. Don't lecture me about tank space. I just want to know the goddamn sexual differences. If you are an expert breeder of pacu or a fellow aquaculturist, or biologist, I could really use your help. Thank you.
