clownfish spawning

so after i finished posting my updated tank thread today i noticed my larger o. clownfish(feamle correct) was not out and as crazy as usual. she has been in the back hoovering over the sand just swimming in place. the smaller male has still been out roaming. does this sound like spawning behavior? were do they prefer to lay eggs, what occurs during spawning? never really researched it.:-/

 

Mine would put them right under their bta... Sometimes on the back wall of my nano cube...

 

Not sure if you can see them or not??? Off to the left...

yup i see em. hmm i dont have an anemone, i do have alot of other things they could host, but they choose not to host anything. would they spawn with out a anemone present?

 

all they need is a flat area to lay their eggs. search 3reef, we've talked about this 100 times on here that I know of.
