Are they really yellow labs?

That is weird. But the problem is...females don't have eggspots on their pelvic fin....Can you try and make them spike of their dorsal fins and see if the ones that have the rounded dorsal are maybe pointed...:)

Maybe their small size have something to do with this?

If i do have 4m/3f, what should I do? Can i wait for them to breed and add more females to my stock? Do I have to take some males back to the store?
 
You can wait and have them breed and then take the one female holding and put her in a QT tank until she spits out the new fry. But imo, I would take 3 males back to the store and have only one male to 3 female. That is the better ratio you should actually have. Because if you have more than one male, the others will chase after the brooding female and try and make her spit out the eggs, or she could swallow them.

What you can do is take out the two or three labs with the eggs spot and the pointed fin.

And another option is to tell the true sex is by venting a fish...

this can actually make them stressful.....but if you want to give it a try, the website shows the difference between male and female...(don't mind the pix...):)
 
AHH FISH PORN LOL

I'll see how it goes, if I see too much agression, I'll do something about it, btw, would you say this is a male: (one in middle)

 
When the male yellow labs are content and happy they will usually only show black on their dorsal and pelvic fins. But if irrated or stressed they will show all black on their dorsal, anal, and pelvic fins.

From what I've seen once their fins develop black markings they're a permanent pattern and not mood-related.

Too small to say (determining gender isn't easy with this species, and with sub-adults it's even a harder task).

The one on the left looks more female and the one on the right looks more male (is that an egg spot on the one on the right)

When we had our males they would have a slight black coloration on their pelvic when they were happy. But, when they were stressed it would turn completely black. I can see what you are talking about though....:)
 
I don't think I can give them up, I think what I will do is add more females to the males.

I think I have 4 males and 3 females, I think I'll get 5 females or somthing.

I'll add 6 aceis and that'll be it for the tank.

There is only one problem though, THEY ARE SO FREAKIN SHY, they are always in the rocks and scatter when i go near them arrggg!
 
They're still fairly new. Once they're completely adjusted and established they'll rush to the glass to greet you (anticipating food).
 
As KB have already mentioned, it's pretty hard to determine the sex visually (without and sometimes even with observing their behavior), female labs can be just as dark around the fins and have eggspots, some can also be as aggressive as a male. Venting when they're mature would probably be the best way.
