Doh! I knew I'd catch something wrong. In question #3, I said " How much can I expect to spend for a 75 gallon? " What I meant was, how much can I expect to pay for a substrate heater setup for a 75 gallon tank. Googling doesn't seem to tell me if it's just the cable or if I'll need extra bits. And finally, the books I own are "Setting up a Tropical Aquarium Week by Week" by Stuart Thraves. It's great, but very much a beginner's book so it doesn't cover a lot of fish.. The other book I own is a secondhand "Aquarium Encyclopedia" by HPBooks. It's large, but old, and technology has outpaced it.
