Can someone help ID what’s wrong with my frogspawn?

Hi,
Welcome to Reef 2 Reef

It isn’t unusual for corals to retract at night. Is it staying open during the daytime or not as much as it used to?

One possibility is the lack of phosphates. Most LPS, including frogspawn, prefer some nutrients in the water. It may be starving.
