He's sitting at 680 grams empty and about 2 1/2 years old. I have placed him in a tub with a female after another male has been in there, and their heat tape gets shut off at night. I know last year my male spider took a few months to actually start doing his business, though nothing was produced by him.

I will try the other males sperm suggestion, I need him to make my pewters, lol.

Thanks for all the suggestions everyone!
