These mushroom corals have already doubled in size! Its been maybe 2 weeks! CRAZY!

But one, I noticed last night, has closed up... is that normal?

Definitely normal for some to open while others close

ok awesome! My shrimp walks all over them, was thinking maybe they are getting angry at it for that

My bubble mushroom, zoas and paly all close up when the lights go out. Just got some yellow polyps via FedEx today, Interested to see how they respond as compared to the others I have.
