Hey guys. I have a 180 gal with a 12 inch highback gold and 7 discus. Things were fine until the discus got stressed out by the aro. The aro doesn't seem to be interested in the discus, but the discus now stay at the bottom towards the back of the tank. I plan to move out the discus. Was thinking of stocking options. I don't really want to keep the aro alone in the tank. Any help would be much appreciated. Thanks
