ive thrown around alot of ideas for my 125 and everything seems perfect but i wanted to add 1 last medium fish for my tank.i want your opinions on which 1 to get.i have a non aggressive system so these are the fish i always wanted butnever owned.powder blue tang,naso tang and a foxface.now i have had success with many hard to keep species.ive owned queen anthias that survived for 3 years and some other species that lived for many years so the powder blue shouldnt be an issue.right now i have 1 blue throat,2 clowns,some cardinals,3 differnt wrasses and a copperband which is 4 years old and counting.i would like to have all three but 1 would be great
