georgah--
Yes, you should have gotten a aperture tool for the fish-eye optic (this is different from the "optic swap tool" which comes with any new optic you might buy and is used to switch from the FE to other optics--
This is what the aperture tool looks like and
this is what the Optic Swap tool looks like). It may sound silly, but the aperture tool might be hiding in the box somewhere....really...it happened to me once... If not, I suggest contacting Lensbaby's Director of Customer Happiness directly:
kirsten@lensbaby.com
I'm sure that she will do all that she can for you--
In my experience, Lensbaby's customer service is excellent--
Hope this helps and Happy shooting in Oz!
