Congratulations on your new fid! He's beautiful! Any idea how old?
Just wanted to throw 2 things out there that you may or may not already know. You mentioned that he loves bells. Bells are great toys, but you should always be sure to remove the clapper. Quite a few parronts have either lost their birds to ingested clappers, or come close to doing so.
And second, it's great that your little guy has settled in so swiftly with you. While it's quite possible that he's simply a very easy going bird who found an immediate connection with you, just keep in mind that some birds go through a "honeymoon period" for a week or two before they start pushing their boundaries.
Sometimes this happens and people who are unprepared for it think their sweet, loving fid has turned into a hell beast overnight. Not so. If this happens just stay patient and ride it through, all the time being solidly consistent with any boundaries you set.
But whether this is a honeymoon phase or not, it looks like you've gotten yourself a wonderful new companion. Congratulations, again!
