Glow-in-the-dark fish

My friend Kristin got two fish today for her office. One is black and the other is gold. She also got some fake underwater grass that glows in the dark. I think instead she should have bought transgenic mutant fish that glow in the dark. They really exist. Take a look at this SFGate article: One fish, two fish, red fish … blue fish?. Apparently transgenic fish are illegal in California, but not here (Massachusetts) and not in Nevada. So if a transgenic fish is swimming in Lake Tahoe, do the California authorities make sure and corral it onto the Nevada part of the lake?
