I bought 5 from Bobs original importation. All were for resale, and went to new homes. one that sold locally was returned to me after 1.5 years. The buyer called me and stated he was getting big, and his girlfriend wouldnt let him build a bigger enclosure, so i bought him back.
This person treated this croc almost as you would a bearded dragon. He let it outside on a harness to get some rays in the summer, let it free range his house at times (supervised times only) and scrubbed its skin off once a week. When he brought it to me, he even took it out of the box easily by hand, but was always cautious. In this time it went from a hatchling to 42" nose to tail tip.
Well, 6 months later now, hes in excess of 4 foot, and isnt quite so docile !!!! He doesnt lash out like my friends cuban cross (its 9' or so) but deffinatly lets you know where you stand with a subtle hiss (not so subtle anymore) or by a half hearted attempt to bite thru the cage. He readily eats from a set of tongs, and jumps for food, but one time recently he jumped just a bit higher than i thought he could and came within 5 inches of my hand, so i think hes being tricky !!!!
Beautiful animals, but as any crocodilian, hes not to be trusted...... after all, we all have our cranky days
