From my experience gold wolves are just aggressive towards their own kind. I kept a trio of golds with about 6 or 7 bichirs and gars. The golds pretty much nipped each other all the time and left the others alone. Now my mala tolerates no one. Well he does let a small mystery snail share his tank but anything else will be killed. And like others have said, my mala is fairly active. I have floating plants blocking a lot of the light and i think this makes him more comfortable because he swims around more than one of my red wolves.
