My clove polyps like less flow, moderate to low light, and slightly dirty water (I keep my nitrates 2-5.) mine took about 2 days to fully open up, but they were shipped. I’d just give them time!
I’d give it 1-2 more days. As long as it’s not melting, you’re fine. If it persists though, check water and reevaluate— as long as the other corals are happy, the clove should be as well. They’re not too picky IME
