Tim has kept fish for 36 years, and started his first fish room in college 23 years ago while he worked in a local fish store. That fish room now has 45 tanks totaling over 2,200 gallons, and has seen the breeding of a vast variety of different species of fish.
After finishing college, he started working at the Toronto Zoo on conservation projects in 1998, which soon lead to his participation in the Madagascar Freshwater Fishes project. Tim has subsequently bred several species of Malagasy fishes and sent them to many other zoological institutions. He has participated in five expeditions to Madagascar, surveying several rivers and discovering several species of fish that have not been described, including species of Bedotia and Rheocles.
