Have you decided what kind of clown you want? My personal favorite sifting goby is the diamond goby. Other then that I'd check out a small wrasse, they're colorful and very active swimmers.
My sand sifter is something else! I goes direclty to the clam and dumps his mouth full of sand on the clam. I kept moving the clam and the goby keeps going to the clam
a colorful goby, I have heard mandarin gobys are had to keep is this true?
Just stay away from those beautiful creatures. Long story short, lots of live rock or death of the creatures.
