Mine do that every couple of weeks. Their rock looks like it has two or three on there. But when they recover, you can't see the rock at all. Actually, mine did that this week. Now the rock looks like it has a big green carpet on it.
YET AGAIN:
MINE DO THAT EVERY SO OFTEN. Even with the lights on. That's how I see it smart guy.
And how in the world did you not know I have ricordia???????
Do you not remember our big argument about how my ricordia were green and so were yours? Not blue like you claimed. Although there are blue ones. Geez man. I have a whole rock full of the things on the right side of my reef.
Come to think of it.... I bought them with you standing right next to me at Marine Fish on Johnson Ferry corkey. Same time I bought that little green brain.
MY RICORDIAS WERE BLUE!!!!!!!!!!!but they died.....I have a green one now though. And I new you had shrooms, but not ricordias....geez, chill... And FORGIVE me for not remembering....For SOME reason, my short-term aint that good these days, nowutimean? Dude, I'm sorry and i know this is off subject, but this chick next to me in the computer lab is going crazy on her keyboard, I think she's on ccrank or something
Anywayz, SO YOU HAVE A RICORDIA!!! fine......
Can you describe this "sleeping"? How about your test results and the specs for your tank?
HairTrigger is right about it not opening sometimes even when the lights are on.
