If your following proper animal laboratory protocols you would not have the problem in the first place. Your fish may already be under stress and you seek knowledge to possibly exacerbate your situation! Perhaps culling the fish after 12 months is better than 18, either way we do neither here, our fish are reliable breeders up to 2 years.

I must admit I was a bit shocked when I saw your subject and I apologize if you took offense to my comments. We are all looking for knowledge but I don't think your subject is proper for this forum.
