Well, honestly, I've got this 6 foot rat snake that, when I got it, had been eating 6 mice every two weeks for 10 years. His cage is a 110 gallon equivalent. So if space isn't an issue, and you just want to feed mice, then you have a huge amount of options. Obviously it would be impractical to get a Boa constrictor and give it 20 mice at a time, but you could get any corn, king, rat, sand boa, ball python... ect.... yeah... snakes are cool. Solid pink is hard to come by, though ;). Pink with spots, they can do.
