i've tried many times to get schooling fish and i realized that they will school at first and at the pet stores because they have fear. When the fear subsides, they will stop schooling. Schooling for fish is an instinctive behavior to survive when there is a threat or fear for their safety. After being in your tank for weeks and months, they no longer perceive any threat and they will stop schooling. Put a predator fish in with your schooling fish and then its a different story.........
