Just wondering do you need a source of light contantly when breeding rainbow cichlids as how will the male fertilise the eggs in the dark when he can't see? Or can they see in the dark? Just wanted to know as I have a breeding pair and don't know whether to switch the light of in the night or not maybe keep it on in the night and switch it off in the day as it would still have a source of natural light through the window.
