Hi Tragic, welcome
What a lil cutie pie you have there! I must say it looks NOTHING like a goldfish! LOL I think you made the right choice

haha
Like illusive said,give your new friend a few days to get used to his new home and surroundings. S/He'll be chirping in no time. First s/he has to feel safe
Talk to him softly lots and lots, and move slowly around him. While changing food/water talk to him and tell him what you are doing.
Playing music is good..they really enjoy music, and after a while you will get to know what kinds of music s/he likes best.
She really is a little doll

Congrats!
