Purple Stylophora Feeding

[Reefsi]

I feed my tank a roti and zoo plankton diet. I feed the tank about 1 tbs per day for all the sps. Whenever I feed the tank about 5-10 minutes later the polyps on my stylo retract in. Its not every polyp but I would say 40% of them do. I will try and get a picture of this tomorrow. Is this normal? Is the coral just feeding?

When the coral grabs the food the polyps grab and retract. this is normal.

These corals can eat a lot. I would add the newly hatched brine shrimp might be something to try as well.
