It's only poor advice if you're attempting a reef tank. I kept my fish alive and happy for four years with one 40W aquarium flourescent. I raised a juvenile emperor angel to adulthood and a 1" panther grouper to 13". I've since upgraded to reef and got a power compact setup.
Anyway, I'd recommend the topic creater do a Google search for any specific question he has. There are TONS of free, how-to sites on this hobby that include tank setup, lighting info, and disease identification. A book really isn't necessary unless you want to look at the pictures, although they can be good for emergency use. Also compare information on more than one site to make sure it's accurate. Always read the "about us" page.
Don't be discouraged. If you're looking to set up a fish only aquarium, all you really need to start with is a flourescent light, crushed coral or sand, salt, a test kit, a hydrometer, a heater, water conditioner, and a good canister or wet/dry filter with high gallons per hour. You probably already have some of this. That's all I started with and all was well. My brother's had an undulate triggerfish for 3 years in a 30 gallon tank from Walmart ($50 with hood & light) and a cheap canister filter. You don't have to run out and buy $1000 worth of supplies when you're just testing the waters so to speak.
