I've had salt and fresh tanks before, but it's been at least twelve years since my last setup. I just purchased a 27 gallon cube and I'm trying my hand at aquascaping in freshwater. I'm trying to choose wisely with only a few fish, but it's hard to restrain myself because there are so many cool directions to go with it. I see another tank in the near future. I'm glad I found this site in my search for inspiration.
