Sorry to hear about your fish. That's rough. Well, since the tank was moved, you might have another cycle, so that'll have to resolve before adding fish. 90g is a good size. If I had that size, I would get a foxface, a couple of bartletts anthias, some blue reef chromis, few bangaii cardinals, a red tail pearlscale butterflyfish (unless you're doing corals too), some kind of Blenny (cause they're funny), and a couple of b/w clowns. That would be a varied mix of color, and they're all beautiful. Of course, they would have to be added slowly. Good luck!
