I just looked them up and those two rat snakes are real handsome animals.
Somebody also suggested egg-eating snakes.
Egg eating would be kinda cool! though they can be finicky. Most asian rats are. Rhinos, bamboos, thai beauty snakes, mandarin rat snakes (another HUGE fave of mine) have some serious attitude but make for an amazing and moderate to advanced snake. Kunashi island Rat snakes are slowly becoming more common and have a great poweder blue belly. the babies start out as brown with a two dorsal stripes and then get green/olive/blue coloring. and they have a natural albino population as well. <3 snakes hah ill hush now hehe
