Male angel fish cant lay eggs, only females. So at least one of them is female. If you want to raise the eggs you will need to actively do so. The likelihood is that the angel fish will eat them after a few days, if they dont do that they will become wrigglers and eventually free swimmers when they will starve if not fed specifically.
My angel fish lay eggs every 2 weeks and have never got to the wriggler stage. Do you want to raise the eggs? You will probably first need to remove them to another tank. Might be best to leave the first batch and plan for the next batch uf you want to get into raising angel fish young.
