Fish don't have families. To a shark mom, their babies are like serving bowl size Big Macs, and fish don't visit their families for thanksgiving. And hobbyists give a shit about how their fish are collected. Plus, I'd rather live in a home with specially made shelters for me, adequate food given to me, no effort required, have no bullies or predators then have to work to get my food, have to have enough energy to find a good sized shelter, constantly worry about predators and bullies, etc.
