Hi - I'm a senior citizen in London, ON, Canada and am soon ready to add fish to my 12 gal. (U.S.) aquarium. I plan on getting 8 or 9 Neon Tetras and one or two other fish, preferably top dwellers but that is not a priority. Does anyone have any suggestions? I've had 2 or 3 larger aquariums but that was a long time ago! I consider myself a beginner again. My tank is well planted and ready for fish as early as Wed.
