Feed LPS???

[Zoaelite]

I find that my chalices will only eat at night time or very early morning but will accept small meaty foods such as Mysid Shrimps, I doubt that not feeding is killing it as most photosynthetic pieces of coral get around than 98% of there energy from sugars produced by Dinoflagellatic photosynthesis (This is from BBC The Blue
Planet Sea's of Life).

On the other hand species LPS that are target fed in my tank tends to grow faster and show much better colors than ones that are not.
