I have a 10 gallon tank that I would like to set up. I had my 29 gallon tank water tested. I had a PH of 7.3 and I don't remember the exact KH and GH but I remember my water was moderatley hard. Are there any small fish other than livebearers that I could get for my 10 gallon? I plan on having 2 mystery snails or nerite snails, driftwood, and live plants.
