Ricky, yes, they will start spawning at about 3-4 months old. Tilapia ARE cannabilistic! If your aquarium water if filtered and clear, you will lose all ofspring. If it is VERY green w/algae about 1% will survive.In the pictures, the dominant male is about 10" and the females are about 8". There are 3 smaller (2 mos old) fish that are the only survivors of over 25 spawns. In the upper right of the 55 gal tank is a small(5x5x8") breeding cage I started using 10 days ago. In the net you can see 100's of fry that are 8 days old and some eggs I collected yesterday. In my tanks, as soon as the female spits out the fry, they are eaten! It's rather obvious that the breeder net will save most of the fish, but I will have to set up at least 2 more smaller tanks to raise the various sizes in.
Dom. Male is lower left
2 month old in center (1 of 3)
Blurry, but shows a mix of red/blue hybrids and the darker blue tilapia. Fry are 8 days old and eggs in upper right are 1 day old.
