I'm glad it's working out for you.
Not to burst your bubble though, if the Parrot wanted the Angel, he'll still take him and having another Angel in there won't deter him. I used to have a mananguense in a 280g tank along with a male red devil that co-existed for years. (among a few other fish) and I put 2 female red devils in there and was going to move the mang out 3 days later into another tank I had set up. Didn't make it. The mang killed all 3 red devils 2 days later.
Not trying to scare you or make you feel bad, just letting you know to keep an eye out for a while. I doubt this will happen to you as the red blood parrot isn't as aggro as a mang or red devil and can't do much as much damage.
Hopefully, he won't care about him anymore though and you'll have a nice setup.
