Alex Zimmer wakes up early when he wants to build a mutant. He needs to get to the lab before the lights come on. The lights are a signal. They tell the fish it’s time to breed.
Zimmer, a post-doctoral fellow at the University of Alberta, studies zebrafish. As creatures, they aren’t much to look at, zebrafish. They’re a few centimetres long. They have tell-tale blue-black and white stripes. But they’re not striking. They don’t jump through any hoops. “They’re just plain fish,” said Marc Ekker, who studies zebrafish at the University of Ottawa. “They’re probably the cheapest fish you can buy.”
