Every critter I have is named and I use those names. To me, they are more than breeding stock or a collection - they are part of the family. I suppose I'd rethink things a bit if I had a truly large number, but I have no plans to have 100 snakes and/or geckos. My breeding groups are and always will be much smaller. So names are how each one is identified.
Although, on the forums here, I do sometimes refer to the one I'm talking about as "my male Argentine" or something like that, in the long run, I can't imagine not calling them by name.
