Angelfish are breeding!!

[Xtasia]

So for right now...

I should just wait for them to lay the eggs.. try not to stress them out, feed them high quality foods...

I read somewhere that big water changes are crucial in angelfish breeding, but every time I do a water change, my 'stud' gets so stressed out he can't eat for a few days... How often should I do water changes? I was thinking I should probably wait until they spawn again, but 2 weeks is a LONG time to wait!
