This is going to be a whole separate blog…but for all intents and purposes, I’ll briefly explain the lighting you’ll need. For freshwater Fish Tanks For Sale, just start with a basic florescent lighting fixture. They are extremely inexpensive, and the bulbs last almost forever. Also, since they are florescent bulbs, it’s easier on your electric bill. Once you get into the more hardcore lighting choices, such as Metal Halides, VHO, compact florescents, etc…the price will increase dramatically.
