Acan echino - size of the food and care

[dendro982]

My guess is that this is Acanthastrea echinata, the damaged one - in the need of most comfortable conditions. What they would be?
I placed it where the blasto merletti, lobophillia and candycanes grow well. Should I increase light or flow, comparing to the corals, listed above?

And the food: here it's eating SFB Sally's mysis. Should I give it something smaller? Is it reasonable to feed it twice a day - will it be able to process the food?
New to this coral. Any advice?
Thanks.

You might want to cut up the mysis a bit but I have seen acans eat larger chunks like in your picture. It looks like it will do well since it is eating all that. Keep it clear of other corals when it gets bigger, they are little killers when they get to close to other stuff. Nothing has won the battle with my Acan echinata.

Will do, thanks. Glad, that ID is confirmed. Pity, that they are stingers...
