I have a 60gal reef with lps and softies and about 110lbs of LR. I have a 2.5 inch yellow eye tang, a pair of percs, and a 3 inch royal gramma. Can I add a fish or two more? If so, what do you guys recommend? I really wanted a lawnmower blenny, but have read it might starve to death. My tank has been running for about 1 year. Thanks!
