Brain Food: What is the feeding mechanism of Trachyphyllia coral?

This week we have been talking about brain corals so let’s talk about how they feed, and specifically, how trachyphyllia feed. Are they filter feeders, suspension feeders, or do they feed via photosynthesis? If one or more of these options don’t apply to trachys, then what other corals feed that way? Maybe most importantly, what is your experience with feeding trachys? Please tell us what you feed your trachy and share any tips that you may have on providing a healthy diet for brain corals.

I've had a fair amount of brain corals during my time in the hobby, and I can definitely say like most other LPS corals they benefit greatly from direct feedings. My oldest piece will be around 7 years old in my care soon. I try to feed my brains about once a week, either pellets or frozen foods. The day after feeding they become extremely puffy. While they are photosynthetic, I believe feeding them directly can aid in their long-term health in a reef tank.

I have the cousin of a Trach....a Wellso, and it puts out polyps that appear to move the food to it's mouth, located in the center of the coral....similar to an anemone. I apologize for the poor quality photos because I have a cheap camera...

Here it is thinking about putting out it's polyps.

And here it is with polyps full out, more typical with lights out.

1. That's a lobophyllia, not a trachyphyllia (or wellso)
2. Wellsophyllia is a synonym of Trachyphyllia

I can understand #2 because up until recently they were considered separate. I'd say the majority haven't made the jump yet. As for 1, how do you tell the difference? I'm interested.

The flesh texture looks more like that of a lobo than a trachy. Trachyphyllias also have larger, flatter mantles and don't have this color scheme of purple with a green concentric ring.
