Aquarium Advice Addict
When I got my first parrot I tried keeping him in a community tank with gouramis and mollies. He harrassed all the other fish to death. You might be able to get away with the danios since they are so quick, but trust me, the betta is as good as dead. It's a slow moving fish that has no way to defend itself from an aggressive cichlid. The tetras and corys will be fine though. Personality varies from fish to fish, of course, but in general parrots can be pretty aggressive, and do better in pairs or other even numbered groups (the odd one out will get picked on). I have 2 that do very well with a school of barbs.
If I were you, I would nix the betta for sure, and possibly replace the danios with more bloodfins. The danios might be ok, but if a parrot ever catches one it will be eaten for sure. Then I would add another parrot. Mine used to live in separate tanks, and when I moved them back together I noticed a big change in their personalities. They seem a lot happier and they hang out together all the time. I really think they enjoy being together, and they are much more entertaining in pairs or groups. If you do get 2 of them, make sure to buy them from the same tank at the same time. This will cut down on aggression, and it is why my parrots couldn't live together until the smaller one grew up a bit. And like FF said, try to buy gray juvies, as this way you will know they are not dyed.
