Isn't T. atratus one of the smaller species (of the ones commonly kept in captivity)? I know the Rossman et al. book says something like 100 cm maximum length, but I was under the impression that most remain significantly smaller?

Anyway, there shouldn't be a problem, but the female might get stressed by the male constantly trying to mate (like mine does). I'd assume that keeping them from babies would be easier than introducing them later on, which in my limited experience isn't difficult either.
