Goliath still not eating!!!

Okay.. I have taken Goliath to the vet as stated in my other thread and he received a clean bill of health. vet stated that Goliath is in breeding mode, hence the not eating at the moment. He said that if he does not start eating in a month or so, to call him back and we'll take the next necessary steps.

My question is this, how long do males stay in breeding mode if no females are available and is there a way to "snap" them out of breeding mode to get them to eat?

any input is greatly appreciated. And mods, if this is in the wrong section, please move it to the appropriate section, thanx.
