I hate to tell you, but most of the stuff used in aquariums is the same stuff you can by at a garden store. For an example, I will used polished rocks from walmart. In the pet setion you can get a little tiny back for like 2-3 bucks. If you go back to the floral department you can get a bag of the same rocks for $1. Oh and you get 2.2 pounds vs. about 1 pound. Yep that is why I asked about the plants. There are all kind of things out there marked for aquarium use that just cost more money. Since I have a breeding pair and am getting two more pairs tonight, I will be doing water changes about every day. Any thing that might come off the plants that might be harmful should be ballanced by the water changes. Thanks again to all.
