If he has a bit of a temper a reptile rescue would probably be a good choice. Some people would take him just because he was free or cheap not realizing what they are getting themselves into but most rescues have a screening process in place and may also be able to work on the temper before he is rehomed. Or a local herpetological society might know someone? I wish I could help but I am just too far away and thus all my contacts would be too.
