What is a sea angel?

Monodactylus Argenteus. It's a brackish fish that has to have more and more concentrated saltwater as it gets older. Here is a list of brackish water fish that would be compatible with that increasing salinity: http://en.wikipedia.org/wiki/List_of_br ... sh_species

Mollies are neat because they can literally handle full salt water, and a lot of the species of goby are pretty colorful. Archerfish get large, so you might not want to go with them with a tank your size. Green spotted puffers can be a bit aggressive, but the salinities (if not temperament) match with your sea angels. Be prepared for your sea angels to eat whatever tank mate goes in there. That's why mollies are probably the best choice; they're inexpensive and breed quickly, so if some get eaten it won't matter because you'll probably already have more via their young or your local pet store.
