So, I was reading in the Giant Gourami thread about how aggressive the fish are. Would a RTGG tolerate a clown knife, bichirs, a datnoid, severums, bala sharks or tinfoil barbs, jaguar catfish, and large clown loaches in a 300g if the fish all grew up together or would it turn psycho on them one day and kill the tank? Which of these fish would be most likely targeted by the RTGG and which would work best with it?
****IME it's a gamble with any GG. I don't generally understand their behavior, hence can't predict much, except mine definitely dislike any other GG, datnoids, and pbass. That is in 240 gal. Once they go into 4500 gal, they mellow up. They establish a hierarchy and after that it is mostly peaceful.
*****I've never kept them with severum or bichir or clown knives or clown loaches or jaguar cichlid. Barbs appear to do ok with them, again IME.
I thought about having an arowana, but from what I've read, GGs end up killing them.
****To me this goes to show the unpredictability. I can't say I've experienced this but I only kept these together in large ponds and tanks, IIRC.
