I started it so I will kick it off!
My favorite saltwater fish is the infamous and crazy Huma Huma aka Picasso Triggerfish!!!! It's not the most vibrant of colors, but what it lacks in color, it definitely makes up for in personality! My little guy is by far the most entertaining of my tanks! Always on the prowl for things to keep him busy! He makes me laugh all the time, and I enjoy his recognition of me when I go near the tank! He is the best!!
And as for inverts, my pair of Skunk Cleaner shrimp! They always eat from my hand, and when I go in their tank for maintenance, they always seem to want to try and clean my hands! Also, they have the most remarkable Red, Yellow and White colors! They molt once a week, so they are some pretty happy and healthy shrimp!
