Mine are doing beautifully in a quiet blackwater community. They share their tank with a school of hyalobagrus cats, a pair of betta channoides, a few badis buxor, and some assorted kuhlis. Got them as adults, and some of the males have now been in my care for over a year without any signs of advanced age or slowing down, so I'm not sure if the short lived nature attributed to these fish because of their relation to chocolate gouramis really holds up. All told, a species tank is far from necessary, and it may even be beneficial to have some small dithers with such a shy species. In terms of fry collection, brooding males should probably be segregated from the crowd any way.
