Need some sugestions

[nemosluckyfin]

Hello Everyone,
I currently have a 40g tank with a small clownfish, Firefish, Royal Gramma, and a small blue sided wrasse. A store called the Coral Reef that is near me is having a huge fish sale over the weekend. I was planning on getting a new fish. I was possibly thinking about getting a valintini puffer but that store might not have that fish for a while. I was wondering if anyone had some suggestions for a fish that would do well in my tank. I would need it to be peaceful and eat things like flakes and mysis shrimp.
Thanks,
Nemosluckfin:fish1:

African leopard has always been a favorite in my systems. Not always easy to find though.

I wouldn't go with the puffer, from experience it will eventually go for coral. If say 3 cardinals would be awesome many PJ cardinals or bangaii cardinals. Really interesting peaceful fish
