Well, I was initially looking to cover my 55 gallon, but I decided to just stay low tech with that. I'm just looking for maybe 1 bag to cover a 10 gallon, maybe 2 for another 20 tall later. I was thinking of just going to Home Depot to look for Schultz Aquatic Soil.
And I don't really know about their fish selection since I haven't really looked at it much. I think I've seen gouramis, but not sure. They have feeder shrimp, that's all I have seen.
