Hiya, I have a tank of around 50 gallons. In it I currently have one bristlenose, 6 neons, 3 green tiger barbs, 3 albino barbs, a pair of keyhole cichlids and a pair of kribensis who all get along great All these fish I have had for around 6 months, and with the exception of the kribs and keyholes, are all quite small. I would like to get some slighlty larger fish, a pair of something preferrably. I was wondering if any of u have any suggestions? My tank seems empty around the middle-Id really like a pair of slighlty larger fish in there. Obviously they'd have to be peaceful fish....I dont want any arguments inside my fish tank!! any suggestions? Thanks!
