nope, never had the pleasure, but! One time I was feeding my fish and suddenly a newcomer, a neon blue cleaner goby, began eating from the pipette. Once I had exhausted the supply he started to move up my fingers. This continued and I found it hilarious until one day he actually started to clean my hand. He was an awesome little guy. Unfrotunately I had to give him away after my recent tank crash and before sickness got em. Although this might've been a good omen, cause I was scared he was becoming vampiric!!;Nailbiting
