I have a 30 gal nano reed tank. I have a clown fish, royal gramma, starry blenny and a prawn goby. I want to add 1 last fish to my tank but I can't seem to find one i really like. I want something more on the rare side that you wouldnt see normally in a nano. The fish I am leaning towards getting is Tanakas pygmy wrasse. Are there any other fish you guys would recommend besides the wrasse?
