Kaudern's Cardinal spawning

[TankCla]

My pair of Kaudern's Cardinal decided to spawn today.:lolspin:
This is my first breeding pair. What should I do? Isolate the male? What chance of survival do they have in DT?

I manage to take some pictures. Sorry about the quality. The Cardinals are in the back area of my 75 gallons tank, between the rocks, in a calm waters.

Finally. One lucky guy.

Congrats! If you want to catch more next time, get a long spine urchin for them to hide in.
