Currently stocking our 60 gallon tank, but the one decision we keep going back and forth on, is which goby to get. We already have a lawnmower blenny and banggai cardinal in there, and plan to get a helfrechi firefish, a melanurus wrasse, a flame angel, 2 ocellaris clowns, a puffer (probably Valentini) and then some sort of goby. Would prefer some sand cleaning potential, but don’t want to starve the guy, so maybe sounds like a diamond watchman is out. Considering a pink spot, but hear mixed things on whether they do much to clean the sand. Would love a biota Mandarin, and their beauty outweighs any need to clean sand, but don’t know how much to believe their stated willingness to take a range of foods (have copepods in tank, and plan to start a refugium, but just an AIO, so nothing major) - any advice or recommendations?
