odd behavior from clownfish

[strifla]

I have had my clownfish for 6 months in a 29 gal tank My female has been staying in one spot for a few weeks now and will not move from the spot

What other fish are in the tank?

Is it eating? I have 2 clowns they more or less stay in thier territory.
Never see them on the right side of the tank

just two clowns it is the bigger one of the two and some snails, several hermit crabs, and a banded shrimp. It comes up to eat but goes right back to the one spot and swim around in the spot and some times it will sit still looks like it may be sleeping

The bigger one would be the female. Could be she is getting ready to spawn.
