As the title asks.. what is that one fish? Further, explain WHY you don't have it yet?
For me, it is a Mandarin Goby. I have always loved how beautiful they are, and their unique beauty would be the crowning jewel on a tank I am otherwise absolutely satisfied with.
I haven't gotten one yet as I do not have a refugium to grow the copepods that I would need to feed a Mandarin. Such specialized dietary requirements make it difficult for many to have that one "most desired" addition to their tanks.
