Deflated Pussey Coral

[essentialcarsales]

I've had it in the tank for approx 3 weeks, it took nearly a week to get settled but deflates severly when the lights are off, Is this normal?
It's in the bottom 1/3 of tank 72 w actinics and 2x 150w halides.
nitrate is 10 ppm but other perameters are okay.
feeding tank with salifert coral food.
Any help would be great.
Cheers

this can be normal as long as it inflates fully when the lights are on i would not worry too much. :)

[P.A.D]

All photosynthetic soft corals deflate and close up during the hours of darkness. This is perfectly normal and no cause for concern.
