Thanks for visiting! I’m a fish breeder and aquaculture researcher. I’ve been culturing marine aquarium fish for sale and research since the mid 1990s.  I also photograph the things I’m passionate about: nature, the ocean, marine life. My favorite photo subjects are sharks, reef fishes, and fish larvae. I’m a fish nut! This site hosts my fish culture research and my underwater photography.
