My clawn fish doesn't eat

[junxu95]

I have two ocellaris clownfish in a 75 gallon tanks for 3 years. Recently I found the smaller does not eat suddenly. He hides behind the rok all the time. Anyone can give me some suggestions what could happened to him?

Thanks,
Ed

He is probably tending the nest.
