Hi all! I have a Top Fin 37 gallon that I'm getting ready to set up and I'm looking for some stocking advice. It will be sand substrate, planted, with plenty of caves and hiding spots. I have a dwarf gourami and a school of 6 neon tetras that I'll be bringing over from a smaller tank, and I know that I want a school of corys (I really want pandas, but open to others). What else can I put in there that will get along? My current tank runs around 7 pH and 20 nitrate, not sure of hardness.
