I have a vieja that is between 4-5" and it seems like it's paired off with my blood parrot. Is this common because before it wasn't aggressive at all really and now it chases every fish except the parrot and algae eaters. I figured it would be to small to breed. I was really hoping that since I did not get pairs of fish that none would breed period because my tank isn't big enough... i will post pics as soon as I have a chance to take them.
