Great video and I really like your angels. I have a breeding pair of Koi and just got in 12 DD Black's about quarter size that I will grow out till they pair off. Yours look very healthy!! Do you have other fish in with them. Are you going to pull the fry out of the tank to grow out?
The female is about 4" long the male a bit smaller. The tank also has two clown loaches. The eggs were there this morning and this afternoon they are gone. I think they lay eggs about once a week to ten days. I have only had them a couple of weeks so the are still not real use to the tank. Plus I keep having to disturb it by replanting the stuff that the loaches tear up.
