Clown (anemone) fish are near the top of the list of cool things I like to see when I stick my face in the water. I think the fascination started before Finding Nemo, but I didn't start scuba diving until 2006, so I can't be completely sure.
I think the little guy in this first photo is a pink anemone fish (Amphiprion perideraion). I make no claims at being a fish taxonomist and I didn't use a fish guidebook, I just looked at pictures on Google.
I think this guy is an orange-fin anemonefish (Amphiprion chrysopterus). This photo would be great for a caption contest, but no one reads this blog anymore so it's not worth asking for entries.
