Hi,

Not an expert but just mere enthusiast here.

I personally might house those two together IF:
* Both are captive breed.
* Same size/age or almost the same.
* Housing is huge enough for them to have personal space.

The main issue here is that apart from territorial claims, susceptibility of one species to certain virus/fungi is differ from one to another but this issue is mainly faced by wildlife-captured rather than captive breed.
