minimum space requirements for a caiman?

[BAZ]

I was curious to see how people here keep their caimans. How much space to you provide, or plan to provide, for your fully grown (6ft to 8ft) specticled caiman or your fully grown (4ft to 5ft) Dwarf Caiman?

I would think that providing anything less than a small room would be inappropriate for a grown caiman. I was planning on getting a Cuviers but I think the water monitors will take up all the space. I guess I will wait until my new house is finished being built to see if I can house one properly.
