New guy needs help

[SuperFudge]

Welcome to the board C&C, :D

I would think that your lighting is on the low side for them to maintain their lighter colour.

They are definatly trying to boost their Zooxanthellea count,to get what they can out of your light.

Food helps,but i dont believe that will help much at all with the color situation.

On a good note,the addition of a metal halide bulb would go along way in getting them back to the way they were.
