How To Know If My Angels Are Pairs Or Just Tolerating Each Other

[superskyway1]

Hi! right now I have 2 angelfish in my tank and I got them at the same time at the pet shop. They are about the same size and around 2-3 inches. I noticed that they swim together and they don't seem to show any aggression. I googled around and I saw that males have bumpier heads while females have pointed ones. Both of my angels seem to have a pointed body though but a little bump on the top. I cannot really tell haha! So, my question is that could they be a pair or are they just tolerating each other?(They always swim together)My tank is a 20 gallon tall. Also, I just wanted to ask your opinion on Tetramin fish flake food. Is it good? That is what I am currently feeding them right now and I give them frozen bloodworms once a week. Thanks!

If there new, Give them a week or two. Normally once they get use to the tank and start feeling safer in it is about the time they'll start taking shreds out of each other.
 
I've had my angels for awhile now and I've never seen any of them go for each other and am fairly sure ones a male and ones a female though. However, Two females can pair just not breed.
 
As for food, Anything. Angels are normally not fussed what they get fed. But what your doing now is pretty good.
