Hi Majikterror. I have been breeding festae for a couple of years now. My first brood was when my female was about 4 inches. They breed in a 72 gallon bowfront. All I feed them is pellets, and the water temp is anywhere between 75 and 85 degrees. However, I just recently had to remove the male, since he became to big and powerful. He hurt her bad one day about 3 weeks ago. I think he can easily be a show fish. He is nearly 10 inches now, as my female is about 6 inches. She never has time for growing, since all she does is breed. I have had thousands of fry, which I heard from many people are quite beautiful grow outs. I originally purchased 8 babies, and let them pair off.
