I'm a lifelong aquarium fish hobbyist and I worked at the Vancouver Aquarium as a senior aquarist for nearly 2 decades. I currently photograph fish and write for our site:

www.fishkeepandchill.com

I also write in hobby publications and contribute to scientific manuscripts.

I am willing to share my images for personal or non-profit use (with a photo credit on each image and a link to my site as shown above), and will also entertain commercial offers, but please contact me first before using any. I can also provide higher-res versions.
