I just bought a 4-5" silver arowana and it is housed with my 5-6" BGK in my 75g and a 4" bala shark. I was wondering what tank mates would go well with the aro. I am thinking of a predator of some sort. Needle nose "gars" have come to mind but am weery because they only grow up to about a foot and they also swim up top so I think there would be a slight confrontation there. Lima shovelnose I believe I will be getting but I just want to be sure it wo uld work out. I also have 2 3" clown loaches that I forgot about. they are currently in a 75g but once the aro grows they will be going in something larger not sure what though. Remember preferably I would like a predator but not one of the real aggresive ones.
