Agreed. Stick with small fish that won't outgrow the tank.
A pair of clowns is always nice. One of the basslets would work. Purple firefish are interesting.
A small flasher wrasse, and once the tank is well established, a dwarf angel.
Pair of clowns, maybe a scooter blenny or 2, some chromis maybe....1 dwarf angel...(dont add 2 angels tho).....as stated above, smaller fish would thrive much better than fish that will grow too big.
