I'd look into the flow around the Gsp. I've had star polyps only open up under a chaotic flow and they can be pretty specific with what flow they are under.
Mine grow like crazy in the shade. They don't need a lot of light at all.
Why I don't think it is a lighting issue Greg. I'd try higher flow first. Then less flow.
Hmm, I'd just leave it be for the next couple of days and see if it comes back out. IMO it is pretty indestructible.
That's crazy, both are really resilient. Have you checked the salinity?
Yeah - it's 1.025.
That's good, can you post more pics?
What type of salt are you using, and what's your water source?
