Can you guys please give me suggestions on good tank mates for my veil tail Angelfish?

Hi all! I’ve had my angel for almost 1 year, in a 30 gallon tank. There are also two African drawf frogs and two mysery snails in the tank with her. I’m upgrading to a 55 gallon tank this weekend and I’d love to add a few more new beautiful fish - I just don’t want to make my angel too upset. Any ideas on what would be good tank mates for her? Should I go with particular fish that are larger than she is, just to be safe? I’d love to know what other fish you all keep with your angels! Thank you so much for any suggestions! 😊
