Stocking a 90 gallon marine, no reef

Hi, my husband and I got a 50 gal acryllic tank about 2 years ago. We have gone more than a year now with no loss of life. I think we made every mistake you can as a newbie. Now I have been gifted a 90 gallon and I want to know if I can add any other fish. Here's my list of what's currently in the 50;



1 Coral beauty angel

2 clowns

1 midas blenny

2 cardinals

1 dottyback

1 small green chromis

1 shrimp

3 domino damsels (I know, they were a gift, I won't do them ever again).



It's a little croweded, I know. The 90 gal is long, so the fish should be happy. I am thinking about a foxface. Should I stop there? Suggestions welcome! Thank you!
