How do you think they school and where in the water?
They only school when I change the water or sometimes when the light comes on. They aren't like Neons or Glowlights. The best schooling fish in my big tank are the Lemons, but their color is washed out next to the CHerry Barbs & Von Rios. The Von Rios also don't school very well for the record.
Oh, and the Cherry Barbs hang out lows to middle in the tank. Every once in awhile they shoot up to the top for flake food at the surface but normally they're making little personal territories amongst the plants. They chase each other playfully but relentlessly sometimes..........................
