When planning this project I thought to get a larger fish tank - this one is a "75G" (made by Advance Aqua Tanks) 48" wide x 20" high x 18" deep, but the larger sizes are basically the same but 5' or 6' long instead of 4', and get much heavier since they are holding more water. Also, if you go higher than 20" it gets harder to clean the tank; so this size seems ideal.
These movies were taken with a Droid cel phone camera - it's limitations are seen here with focus, slow shutter speed, and sometimes problems with color balance.
See DIY fishkeepers for do-it-yourself ways to build everything needed to enjoy this hobby inexpensively. Buy only what you need and don't buy cheaply made stuff - remember this is life support equipment for your pets! Lastly, fish are a lot easier to keep than corals and even have some personality!
