Your Leporinus Fasciatus will eventually eat the Cherry Barbs and probably pester the Gourami to death, they seem to be very partial to fish eyes. I'd be very careful with these fish around smaller fish than them.
Actually the Leporinus died during the move so they are no more in my setup Lol and they were actually very gentle I was surprised fast but nice fish I kinda miss now... Just bought another Cichlid, found a way better LFS not to far from home.
