Well after months of breeding I have managed a way to keep 90% of them alive and healthy to maturity. Basically a Tupperware container from the dollar store that i poked holes in and then i attach the container to the inside of my tank with a old left over power head magnet. This is going to sound weird but I also NEVER feed them. Feeding I believe leads to their death as well as moving them to a small tank. Also I do not take them out of the fathers mouth. I wait until he releases them into the tank. By that time they are large enough to eat on their own. I find that the holes in the Tupperware container allow rotifers and copepods to enter and meet their demise with the hungry guys. So now I have a 16 juvenile cardinals to sell to the LFS. I have a pic of one of the babies in my LTA anemone in my album.
