Best companion for a green cheek conure?

I have a budgie and I'm thinking about getting a second bird. Should I get the same species or would a different one be okay? Worried about them not getting along.

Interesting take! I see your point but I've had a completely different experience. My lineolated parakeet actually...

This reminds me of when I first got Snowball. I was so overwhelmed but looking back, those early days were actually really special. The bond building phase is tough but beautiful.
