Before you spend too much money on a mate for her read up on caramel female fertility issues. I still don't have a good feel for how often people are able to get good eggs out of them (or maybe better put what percentage of eggs laid by all caramel females last year were good vs. slugs). If you still want to go for it a visual recessive male het for caramel would be awesome (hopefully produce double hets and caramels het for the other recessive). Also read up about kinking in homozygous caramels. Wish I could tell you how to avoid both issues but I think it was just dumb luck that I hatched three caramels last year and only one small tail kink in the bunch. I'm still working with the project and have high hopes we'll eventually all know how to work around these issues but everyone should have been warned before investing in caramel projects for many years now.
