should i feed my acan's and chalice's?

So i have two acan frags and a chalice. I was wondering if i should buy some food and feed them to keep their color or should i just leave them without food?
Thanks

 

IME with acans and chalice's the color doesn't have anything to do with feeding them. i've gone months without feeding them and their color is fine.

when I do feed regularly (once a month or so) some bits of meat, they grow quicker (though both still grow painfully slow). but I see no change in coloration.

 

I agree with Peredhil, you can if you want to promote faster growth, but it's not necessary and IMO, feeding doesn't really affect the color.

 

Ok then so maybe just feed them a piece of meat once in a while? What kind?
Thanks

 

whenever I have a fish die, my corals get fed I just chop them up and target feed. My chalice had some wrasse last week

 

wow that is awesome> never thought of choppin up fish?

 

You should feed all your LPS!

I disagree with the comment about the color.... to a point. Some red/pink/orange LPS like acan and chalice will get great colors from frozen cyclopeeze! Other than that, I notice the different with lighting for the most part.
