ok well heres my .2 :
when someone posts that they are getting an exotic animal and they have no idea what ts needs or how to keep one , everyone is always going to advise strongly against it. Even though most say leave the guy alone he has two other crocs, doesnt meant he can handl a third more dangerous croc. Has he even shown that he has planned on how to house the current crocs he has whn they full grown?
Its like us with the our monitor, there are TONS of monitors my husband and i want and could easidly get know that they are small. but we know that its already going to a be a project enough that we have to figure out how to make a proper home for the one we have the we know better not to get 2 other monitros that grow 4'+. Its like if in fish keeping a noob gets a 29g with an oscar, ok honest mistake, they didnt know the oscar needs a much bigger tank when adult size and they are now trying their best to figure how on earth they are going to get a large tank so soon. It would like if that person on top of knowing its going to be hard to house that oscar, went the net day and bought 3 more.
Im just saying on one hand most are saying leave the guy alone and such but he came here for advice and its is perfectly fine that people are advising against it and lisiting obvous reasons why.
to th op:
i dnt thik a salty is meant to be a pet at all, and its a shame they ar selling them as pets. its can easidly kill anyone. concentrate on properly caring for the ones u have and consider what they will ned in the future in terms of housing and feeding and then think if its possible for u to triple that in order to keep the salty.
