Zig and Zag...

They are very pretty. How big are they? They look huge!

 

Are they aggressive toward each other or extremely passive. Usually a male and a female will bicker back and forth in a somewhat gentle manner. 2 males will usually beat the snot out of one another and 2 females will just ignore each other for the most part.

You should not see 2 males swimming together cleaning rocks, moving substrate and vibrating near each other. 2 females will do that though. A male and a female will do that and then spawn.

Have you seen the fin vibrations yet.... at about 7 inches they are around a year old and should be practicing at least if you do have a female.

 

Nice Albino!

 

You have either 2 females or 1 male and 1 female.... lets hope for the latter!

Do they dig around together yet in the substrate? Also get a slate and place it in the tank slightly covered by substrate. My Oscars started moving sand to get to the bottom of the tank.

They should if you do that after a while pick up the gravel (if you keep gravel) with their mouths and move it away.... that means they are working towards breeding. If it is sand they will shovel/fan the sand away. This may go on for months before they spawn. When they spawn you need to be their to look at their breeding tubes to be sure you have a male and a female. 2 females will act like a pair but the eggs of course will never fertilize. The 2nd female has even been known not to lay eggs but to look like she is a male fertilizing them. Dont go by behavior as much as what you see when they are ready to spawn.

At 7 inches they really shouldnt spawn till about 8-10 inches which will come before you know it but still not soon enough for you I am sure.

 

Check their vents, sure fire way of figuring out the sex.
