New Friend for Clownfish?

[New2reef]

Hi!

I'm a new by, but have had my 125 setup for 8 months now. I have a few SPS corals, a cleaner shrimp, snails and hermits and a lovely mated pair of clownfish. i got the pair about a month ago, and after some initial shyness, they happily roam the tank. i do not have any nems. I am thinking of adding a tankmate, perhaps a cardinal fish or green chromis, I am worried about the clowns being aggressive. any advice?

thanks!
christy

i am by no means a saltwater expert but i know cardinals and chromis both need to be in schools

Yes , would 3 (of either) be a good number? thanks for your help
