hello, im wondering, could i use the plants i buy at the lfs in a "freshwater" tank, such as a tank that i would put north american species of fish like trout, or bass. or would i need to get native plants. has anyone on this board done something of the like? having a tank of this sort, and would be willing to share any experince or knowledge. as of now, i dont have a tank for this, but im planing to get a 30 gallon, or maybee bigger, tank, nad generally decorate it like the natural habbitat of the fish im putting in, ie, driftwood, sand, rocks.
