Clown keepers help

[mikemc75]

I have a black and white clown. In a 55 gallon reef tank with a blue dotted goby. The clown seems happy. I'd like to add maybe a pair of clowns. ? Of what other fish
Suggestions ?

Thank you.

Make sure it is the same species and a little smaller or around the same size as the one you have now.
