Thanks Muske and Balrock043 for your advices.
What is not clear for me; incase I arrange a spawn, in the spawning tank, do you mean that I have to put a male into the same tank, to fertilise the eggs? If so; how shall I know which male is ready for this, or any? And next, when I put this male into the tank, after the female eggs are laid, will the male not eat the eggs?
