Jack Dempsey. I know a lot of people say theres a very shy but mine has tons of personality. He is followd in close second by my Jaguar. I once had a colomian shark catfish he was very cool too. He used to do 1000's of laps around my aquarium. I called him my marathon catfish.
My favorite!!! so hard. Well I would love to have a dwarf puffer. They look soooo cool. And all plecos. I have 2 clown plecos. Also it's not a fish but ADFs are awesome.
My favorite has got to be the Mandarin Dragonet...I hope to one day be able to keep one...but they are so demanding. Baby steps. I'll get there eventually, but for now, I'll take good care of my single Dwarf Gourami.
Here's a picture of the psychadellic beauty that is the Mandarin Dragonet:
