I always love to see new dwarf caiman owners that actually researched before buying it makes me happy. We have a little cuviers dwarf named thanatan. He's both awesome and challenging. When we got him he kinda upstaged our green anaconda for what gets my fiance's attention the most.
Heres some things you may or may not know, but I found helpful starting out.
Dwarfs grow kinda on the slow side in my experience, but my experience includes retics that grow really quick so I my definition on "slow" may be a little skewed.
The bite from a baby is pretty much harmless, but I would make sure you not only research their care but also their proper handling cause when their older... yeah, well, you'll see
Im going to say the closest thing to it would be maybe if you've ever tried to move an angry monitor lizard.
Another thing to think about is finding a vet in your new city. Finding a croc vet is D@MN hard to do... When their older your vet will want to come to you instead, which will cost you- believe me....
If I could make a suggestion, based on my opinion only... I know that sites will tell you to use a ten gallon or twenty gallon at first. Dont. Its a waste of time. Glass tanks in general are. they just arent wide enough... If you have a little room, we rigged up a good sized tank out of a rubbermaid -50 gallon watering trough we bought from a feed store for $100 its about 4.5 feet long and 2 feet and change wide and only about 14"tall. Huge for a baby definitely room to grow for your first year and then some. A cheaper option that would be smaller is a plastic tub like say 124qt or 90qt rigged with hardware cloth in the lid. Now some people will say that a baby will need a smaller enclosure for security like snakes do, this has not been my experience, and that reflects my opinion.
Although they are not pets per se (surely you know this by the time you are looking into getting one), and you really wont tame the guy....
Dwarf caimans are awesome little critters that I would recommend to anyone who "has the passion"- you know what im saying- and knows what they are getting into.
Good Luck man, be sure to post up some pics for us!
