Anemone looks "ok" ... it's bleached, obviously, but most are from LFS. Gaping a little but that could just be accilimaiton. Your tank looks very "new." How long has it been running?
You will need to target feed this animal and give it good lighting for it to survive. This anemone should be a brownish color, not white. Keep your water stable, regular changes, good circulation, light, and target feeding and you might do ok.




They need a sand bed
There is no general of thumb. H. crispa live on the sand, bury it's foot in the sand, period. It won't be happy unless it bury it's foot in the sand. If there are no sand it will wander to find it.On occasion, they'll prefer higher lighting that is found on your rock. However, this is definitely a general rule of thumb.
