Help me pick a centerpiece fish as I plan my upcoming 300 gallon inwall. Tank will be mostly lps but some sps as well. I will have a pair of clowns, pair of b. cardinals, plenty of bartlet anthias to school, a few colorful reefsafe wrasse and many other smaller fish. Looking for one or two fish that will get larger that will provide a nice contrast to the small fish. Qualifications: friendly, colorful, and interesting. Thoughts?
