Wow the colors are stunning! Interesting species, just looked them up. Your DH will like them I bet if he just gives the bird a chance. But that's my bird loving view speaking up lol.
My mom kept a sun Conure a long time ago, and Charlie was an awesome fella. Its a cousin of the bird you are looking at. He didn't let Dad near Mom, or any thing else tho he imprinted on her only The type do connect to a family and outsiders may not be accepted well. Charlie had cage time and open free time in the house. Dad didn't have a lot of interest in him sadly. He likes chickens more, and Charlie literally attacked him one day because Dad gave mom a hug..So I found him a bird rehabber and rehomed him. I worked way too many hours a week to take him myself then.
I know you work hard to bond with anything you have so I bet it will be an awesome addition to your family, they just need to imprint on anyone living in your house.
