Possible angelfish breeding

[YunoGasai212121]

I have 3 fish in a 29G tank (the tank is about a week old). Fish 1 (female) fish 2 (unknown/most likely male) fish 3 (male). I’m not sure if how they are acting is mating. Fish 2 and fish 3 fight a **** ton and act like the want to kill each other. Fish 1 and 2 sometimes fight but it’s not as bad. Fish 2 does this thing where he swims really fast at fish 1 and than like stops and barely touches her. Fish 1 and 2 also do this thing where they like peck at each other’s chests not super aggressively. Fish 1 and 2 are usually near each other while the other fish is usually separated or chased behind the filter. Also I saw fish 2 and 3 lip lock so I’m not sure if maybe they were fighting over the girl.
Pictures:
Possible mates fish 2, fish 1

Fish 2 on the left fish 1 on the right. Right before they peck each other’s chest

Can someone please check their genders if they can because ik it’s hard to know

Pretty angels! I think the two in the first picture are male and female

When she is ready to spawn her vent will drop. It will look like a symmetrical tube. If the first two are male and female then that is what the bickering is about
