As I was browsing through the fish isle of WalMart around the start of this year (which means this light is still working today after lots of use) I came across the
Tetra ColorFusion LED light for around $20. This light clips onto the inner tank hood rim of the aquarium (cord has an additional clip to go around the side) and gradually rotates through several colors which allows you to pause the color rotation and keep the light on a shade of your choosing (and to turn it off you hold the button down).

| 2.5 Gallon Aquarium Setup with the Tetra ColorFusion LED Light |
This LED light has 3 primary colors (blue, red, green) and 1 neutral color (white), and you also get a few various shades in between during the light rotation (purple, turquoise). This is a true led light so it brings out any metallic sheen, neon, etc on fish and/or decor (it's actually quite nice). This light in my opinion isn't that bright so I don't feel it would be enough to adequately grow plants (or cause algae growth) or use effectively on a large aquarium as this mainly makes for a nice night time aquarium mood light. This unit is waterproof which allows me to top off my little 2.5gal betta tank (pictured above). Overall I would give this 4/5 stars, and I'm going try this on my goldfish tank because mine don't really care for bright lighting.
