What are the symptoms? It might just be frightened and hiding.

FYI: Clownfish are best kept in singles or pairs. Three is asking for aggression problems.

Ths symtoms is that it's trying to bury itself between Rock and Sand, its fins and tail is still moving/swimming though, ...... he is the biggest Nemo of the 3 ... my daughter is affraiding that that Nemo will die and she can't sleep :-(

We'll need more information to give you any meaningful answers.
What are your other basic water parameters like ammonia level, temp, salinity, etc.?
Describe your setup a bit (ie. size and age of tank, filtration, etc.)...
