I am trying to decide what I want to get while my tank is cycling. This is my first "real" tank so I went to the LFS the other day and liked the neon tetras. I was thinking about 5-7 of those, and maybe a cory or 2. However my GF thinks that might be boring. Is there another fish that I could add just 1 of to change the look of the tank. I also have been searching around and foun olive nerite snails. These seem like they would be cool to add. How should they be considered when choosing fish as far as size and tank size are concerned. I could do these instead of the corys and add the recommendations you all make here. Thanks for the help.
