From what I have read, neons are shy. Recently I was considering taking my 3 remaining neons out after buying a severum and an eartheater. They have been sharing the tank with clown loaches and tetras. But to my surprise, not only do ALL the other fish not harass them, they are the first to come up and eat, and they actually chase the eartheater away from their food! And I must mention one other interesting habit. Late at night when the lights are out, they appear to sleep (if they sleep) completely vertical! And sometimes spin like a top.
