Are these two photosynthetic?

[Reefmack]

Hi. I'm not sure of the species on these - an acanthastrea and a favite. Pictures not optimum, but the best I can do till my new camera arrives. I've done some searching for a while but can't find the answers I need.

Are one or both of these considered photosynthetic? If not (or even if it would just be beneficial) what the best food for these?

Thanks much.

yes photosynthetic
yes feeding would improve their colors and growth
feed mysis or krill or something similar

Thanks for the information.

First one is an Acan Echinata. second one could be a couple things. Favia or maybe Barabattoia amicorum. Both are photosynthetic but will react to target feeding. Keep that Echinata away from other corals. In a battle, echinata ALWAYS wins.

Thanks for more info. The second should be a favia sp., as the guy I got it from raises corals for a living, and I'll have to trust what he says. I do plan on target feeding - started last night.
