looking for fish

Im looking for colorful fish for my tank
and it has to be big, well 4" plus
so far I have 2 ocellaris clowns, lawnmower blenny, cleaner shrimp, 6 blue hermit crabs and 4 turbo snails
still thinking to add 2 cardinals and 1 royal basslet
also I will be adding few easy corals in near future
the tank is 45 g with 78 pounds of rock and plenty of caves
just need that one more fish that will look big and fun to watch
hoping you guys will help me find it

 

I think that you could probably get away with Cirrhilabrus rubrisquamis. They really pop in color, are reef safe, grow to about 4 inches, are easy to take care of, and are peaceful.

 

Dwarf angelfish, some species grow to 6 inches.
