I actually see this combo quite often...with all types of arowana including jardini.
I am currently doing it...and I have done it in the past with success.
I have kept giant gourami with silvers and asians.
If you are going to try it make sure the fish are of a similar size. Tank size will also play a part..I do it in a 600 gallon tank.
I also have a RTGG with a silver in a 240 gallon. However the RTGG is definitely the more dominant.
Success with this combo can never be guaranteed though.
btw this is all with near adult fish...I have never kept them together as juvies.
