I'm a fish physiologist / biochemist and I've been sporadically working on Loricariids since about 2000 (Pterygoplichthys pardalis and P. gibbceps). I'm based out of Canada but travel to Manaus, Brazil every now and then to work on catfish in the Amazon. I mainly focus on cardiorespiratory physiology and metabolism but I'm also just generally interested in armored catfish biology. They have some pretty unique adaptations for surviving harsh environments.
I'd eventually like to start doing some work with them in Canada and this looks like a great spot to both find fish and learn how to hold and maintain them.
