I looked into this kind of stuff when I went on vacation to Hawaii. Was going to bring back some dead rock to put in my tank.

The laws are nearly identical for Canadian livestock/rock.

Legal reasons: Don't do it, it's illegal.

Ethical reasons: Don't do it, it's biological torture.

There is no one physically stopping you and watching your sneaky endeavours, and you think you're saving yourself money with free livestock. Still not a good idea.
