current informal 'research' says a big NO.
i have several male and female jax and by mistake had a situation where one male and one female could see eachother (side by side cages) i kept wondering why the female AND male weren't eating as much, seemed a bit smaller than my others, were always hiding - until one day i took one cage off the counter and realized that the side they shared hadn't been visually blocked. once i blocked it (w/ styrofoam sheeting) there was a change in both of their behavior, for the better.
