A few weeks ago I was at Underwater World at the Sunshine Coast, Queensland. I wanted some fish photographs for the OzWildlife web site. Most of the shots I took were with the Pentax K100D and 18-55mm kit lens.

Shooting fish in the well lit reef fish tanks went ok - the main thing to watch is that you shoot at an angle to the glass/perspex when using flash otherwise you get horrible flash reflections.
