IS it normal for sun coral to spawn? I have a sun coral in a 30g with no light and target feed then couple times a week. The other day I took down the 30g and found bunch of yellow specks on the bottom of the tank and on the rocks. When I looked closely, they were tiny sun coral polyps. Just wondering if they were spawning cause they were stressed?

I'm no sun coral expert, but I think they spawn because they are happy. Congratulations, your a father now.

Yes, Tubastrea species will "broadcast spawn" resulting in little colonies forming elsewhere in the aquarium. Sounds like you had the coral for a while, which as Moses pointed out means it was "happy" enough to spawn. It is true that that Tubastrea (and other coral) will broadcast spawn (if they can) in a last ditch effort to reproduce while stressed. Generally this happens with a specimen that's been through a rough transit, is in rough shape, and not happy in their new tank.
