Only time will tell what variations in color you are going to get. Have you raised baby angels before?? They will survive on newly hatched brine shrimp eggs. If you haven't already done so , go buy some at the local aquariium store NOW and they take 24 to 36 hrs to hatch - so you may want to start working on that. The babies wil not eat until they are free swimming and their yolk sac has been absorbed. After that, they will need to eat every 2 hrs -- it may be hard to see if they are eating - but if you see their stomachs turn orange (the color of the baby brine shrimp) then you know they are eating. The water you hatch the brine shrimp eggs in will turn bad 12-24 hrs after they hatch, so as soon as one batch hatches, start another batch going.
