You have LOTS of room.Some fish that are cool that would be able to go with that tank are discus, silver dollars, MAYBE a few tinfoil barbs, ghost cat fish, neon gouramis, ghost knife, clown loaches, kuhli loaches, dojo loaches, more platyies of different types, rainbow fish, rosboras, longfin skirt tetras, peacock eel (I have a cool female!), and other fish at least an inches and a half (cuz of the angels) that you like!Guppies and neons might get eaten by the angels.
