History of wild Jacksons in Hawaii
OK so this pet store ordered some jacksons from a so cal importer the first batch came in healthy ino what a supprise so he ordered another shipppment this one came on serverly dehydrated and malnurished so he figured that he could house them in his backyard and retrive them when they were back to health. Well that didnt work out and they chams spread thanks to many factors like people taking them home for pets in their backyard and motorists stopping by to pick up these strange little animals and releasing them into other parts of Hawaii. Another population was established there when the Fish and Game services raided a pet store and a door was left open and away went the chams
