http://forum.aqua-fish.net/ A forum devoted to aquarium fish, plants, techniques and fish keeping as a whole. en http://forum.aqua-fish.net/?topic=neon-tetras#1 I have 3 neon tetras, is that enough to keep them happy? original post: May 12, 2007, 1:14 pm egg131313 2008-05-03 http://forum.aqua-fish.net/?topic=neon-tetras#2 Definitely no. Go and buy another 7 at least. You’ll see how happy they will be. After introducing them into your tank they should be shy for a few hours, but after they become friends with currently kept specimens they’ll swim, eat (and simply everything) together . This is my personal experience. My ex had 5 Neon tetras in her tank and it was terrible sight. jan 2008-05-03 http://forum.aqua-fish.net/?topic=neon-tetras#3 agree there Jan,neons should nrver be kept in groups of less than 10.Not only does it look better but as they are a timid fish it will give them agreater sense of protecting themselves , swimming around in larger numbers. Neons should never be added to an immature tank either mickey 2008-05-08
