zoo's closed up ?

[hangles]

I have a small frag of neon zoo's with red skirts. i got them about three weeks ago and they have been fine. even got about 5 new polips. yesterday they closed up and are still closed this morning. i checked my water peramiters and they are ok ! they are in medium current. low in the tank 75g . under 260w pc 420 act and 10k's. i did a 10 % water chang last night just to see if that would help. it didnt !
any help would be great. thanks!

Something might have walked over them to close them up. Give it a day and they should be opened back up.
