yup but its not like he wont have spent 4 times that amount feeding the lizard lol. adults that are healthy tend to life longer stay healthier/recover better from sickness than babies or juvies. depending on species a big lizard can go for 300-4000 bucks. the adult monitor tht was 4 grand was some type that looked like a mangrove monitor but was 5 ft long and is dosil compaired to niles or savanahs. just depends i only got 450 with the cage for my nile lol.
