Re: Containing plant growth You don't need to spend big bucks on a fancy substrate. Clown puke gravel will do, as long as it is small grained enough. If the substrate is too large, then it becomes a problem maintaining the plants rooted in it.
I'm not sure I understand what you're after. Healthy plants = growing plants - eventually they WILL spread, even slow growers. If you're after having a couple of plants in the tank which won't require much maintenance - it's definitely doable. Get a Crypt (wendtii) and/or java fern or Anubias, and basically you're there. You won't be able to get a ground cover, though, as most of those will require higher lighting and supplementation for nutrients.
Hope that helps. |
