Just one question.. why Reptilian Fangs? The reason I ask is, I think you'd be more successful without such a morbid, dangerous-sounding name. Plus the fact that not one of your reptiles has fangs.
Just a suggestion, take it as you wish. As for your reptile list, I think you should probably have a significantly bigger list than that for an educational show. I have 28 snakes, many of which are adults, and even I'm holding off on the educational show business until A) I have more experience, B) I have more adult specimens, which is what people really want to see, and C) I have more reptiles than just snakes.
That's my $0.02. But, best of luck to you with your educational shows.
