I really research my fish before I pick any species. I like fish that are not going to eat each other, easy to care for, are going to be visible and not hid all the time, and that don't harm my beloved ricodia and zoo's. So I am lucky to have an aquarium full of fish that I love. My perc clowns are always front and center and it was fun when they laid eggs and had baby Nemos. My mystery wrasse is totally cool and always checking out everything. My diamond goby ("Curmudgeon") is the fish that makes me laugh the most because he is always sifting sand and rearranging the sand to his specifications. He loves finding his little trinkets and carrying them around. But if I think about the fish I always look for first, its my Midas Blenny. Just like Spider Woman said earlier, they are beautiful fish and so interesting to watch.
