1. Longnose hawkfish. It's been with me for a year now; oldest fish I have and has survived 3 tank crashes (and 3 rounds in copper ) as well as 3 upgrades. Tons of personality, and gives me a "FEED ME" look anytime I'm close to the tank.
1B. My supermale Lineatus. Why? Because I got it for $35 as a "velvet wrasse" from the LFS. After I had him confirm the price multiple times, I informed him it was a lineatus wrasse. He still honored the agreed price, however vowed to be more informed of his fish, hahaha.
1C. Moorish Idol. Never understood the fascination with them until I owned my current one; now I am trying to ensure I do things right to keep him with me for a long time.
