ok i am going to start out with tillapia before i move on to the other fish. im going to raise just about 10 mozambique tilapia in a 100 gallon sea clear show tank that my freind sold me for 300 bucks with a heater, gravel, airator, and i get to keep it in her green house as long as i teach her when i figure it out. im growing tamatoes, oregano, green beans, and carrots but im not sure if they will grow. im trying a water temp of 73-76ish. i was wondering how long it takes the mozambique tilapia till they are ready to mate? i think im starting with 3-5 inch ones. i have heard any where from3-4 months to 2 years till they will mate
