depends... I hear that they will all school together and then break off into their own schools... most likely they will stay separate. Really depends on how much room they have. What size tank were you thinking?

Depending on the body shapes, some tetras will school with others. Depends on the fish though. I can tell you from experience though that one large school of one type of fish looks much more impressive than a bunch of odds and ends. You don't have room for more than one school of fish in a 20g tank anyhow. Make sure you've read up on cycling a tank, especially with neons, they are very sensitive to water conditions. Take a peek at the link below or the freshwater stickies.
