I forget the screenname but the person with Brett Farve did a similar project (you can search for the thread) and ultimately ended up scratching the tropical fish part. If I remember correctly, temperatures were the reason.
According to the climate chart for Visalia, CA on Wikipedia, temperature drops well below "tropical levels" during the winter, and so your only chance of sucess would likely be to bring your fish inside before the temperature drops too low.
However, I guess your question was "what can I stock it with" rather than "will this work", in which case I have to agree with Lupin.
