i dont have much money and need help

I really can't recommend any, because it's not a good idea. If you got rid of a couple, (not euhanize, but give/sell them) Or a separate place for your betta you could maybe get 1-2 ottos, but still thats pushing it.
 
ok i wont add anymore but one of my gouramis is really agressive (has gotten a darker color) and another is a really pale color (its always been and is not sick) can anyone explain
 
Overcrowding, too many fish that should not be together in such a small space being forced to live with one another... again :troll:
 
Seriously, that's actually too many fish for a 10g. You need to do more research as far as the max size of those gouramis.

You obviously haven't seen a full grown kissing gourami.............I wouldn't even keep one in a 10g.

As the others said, give it time and when they grow, they'll fill in that tank really well.
