Is anyone familiar with Fish Tycoon?

I discovered it last weekend and have been completely addicted since. It is so simple, and has me constantly going back to check my tanks for new fish!

It's an excellent game to run at work (if you're allowed!). It runs in real time, so when you check the tank every few hours you can see if your new babies have grown up to become new fishes!

I've managed to breed 3 of the "magic fish" so far... but it's a slow processes.
