I have had my first aquarium, a 10 gallon, for about a year now and have had a lot of success, so I am going to be upgrading to a 20 gallon tank. My tank currently has a dwarf gourami, 5 neon tetras, 2 otos and 2 ghost shrimp. I would like to add some more fish once I get my new tank set up and cycled, any suggestions? Also, what would be the best way for me to move my fish over to the new tank, without causing them a lot of stress?
