Two Questions

[nrbelk]

First question - feeding sps at night - polyp extension.

I notice at night most of my sps have a lot larger polyp extension than during the day. Is this when I should feed my coral?

Second quesion - some coral loosing color.

I have some coral that has never lost its color, other coral darkening to a deeper shade of the color it came as, and finally, some coral becoming more washed out. I check my parameters weekly and they are stable and in the required zones. What other effects might cause coral becoming faded. This fading process is about 2 to 3 weeks.

Once coral that faded on me I moved back down to the bottom of my tank and it has started to gain some color again. These newest coral that is fading I started at the bottom of the tank but still in direct light. Should I move them to the shade?

If you are going to feed your corals, yes nighttime is a good time to do it. This is when i normally feed my acans. I don't specifically feed my sps.

If a coral's color is fading on you in its current location, moving it down is definitely a good plan. Every tank is differently and what works in one tank my not work in another. I have many corals that are described as 'high light' that do better in the shade in my tank.

Although the polyps in my sps tank are extended more at night, i dont see them retract after adding food (oysterfeast). This looks to me that they are not eating it......
