Do different colors of light affect the growth of goldfish?
No, but all fish require a full spectrum lamp and colored lamps should not be used in aquaria. Top • My question deals with the right amount of light and the correct quantity of fish. Ive reviewed extensively the answers and articles you provide about these issues on your wonderful website, however I find myself at odds.

Regarding light, one reply noted that 3-5 watts of power is adequate for every gallon of water. However, in another reply 7-10 watts was advised for every gallon.

However, it was advised to a fellow enthusiast that a 75 gallon tank will support 18 inches of fish. Now that doesnt exactly follow the one-inch rule now does it? Perhaps these answers conflict due to the varying nature of each tank
