Suggestions for new fish

[t1a1c1h]

Hi, we're looking to add some more fish to our tank. It's a90 gallon mixed reef, current inhabitants are
Pair of common clowns
Orchid dottyback (used to be a pair but the male has died)
Solar wrasse
Midas blenny
3 blue star alleni damsels
One bangaii cardinal (used to be trio but 2 killed by a gorilla crab)
Also hermit crabs, conchs, snails, tuxedo urchin and peppermint shrimp clean up gang
Was thinking perhaps a Sankeyi dottyback as ORA have cross bred orchids & sankeys? Or more damsels to make a bigger shoal? Possibly a bottom dweller goby/ blenny?

What about a hawk fish or goby? Try to fill up the space not currently occupied.

I would re-up your bangai cardinal school! You could also add a dwarf angel like a flame or coral beauty. Maybe another school of a different fish like a firefish or dartfish. A goby like a pinkbar would also be nice

IMO, a African Dwarf Angel or a Tomini Tang.
