As long as your feeding enough food, have enough hide spots then you'll be fine. both are territorial, but not aggressive. long as they can each have a hide spot they are comfortable with you shouldn't have issues, though occasionally you do see aggressive specemines of either ( imo this is gender based and since its very hard if not impossible to sex either species, trial and error) just like introduceing any new fish, keep an eye out for any aggression/incompatability issues.
