clown fish layed eggs on glass

[prodogg02]

i noticed today i have half developed baby clown fish stuck to my glass had the pair for 5 years and this is the first time i noticed them.all the other fish seem to know there there to as they try to eat them already i know they wont last in there.is it worth it to set up a new 10 or 20 gallon tank and try to raise them.also will the parents eat them once there free swiming.thanks for any info
