The key to growing plants in your fish tank is the lighting. Most plants require high levels of light and if you have tried to put plants in your tank only to have them wither and die after a few weeks, this is most likely the reason. It’s a simple matter of getting a brighter bulb for the tank and you can have lush green plants that give your aquarium a natural look.
Planting natural aquarium plants is quite easy. Most plants you buy will have a root system which needs to be planted into the substrate. To do this, grasp the root end of the plant between your thumb and first finger while making a little hole in the substrate with your free fingers. Gently push the roots down into the hole and hold in place while swooshing back some of the substrate to cover the root ball. Rootless plants can be planted much the same way, instead of pushing the roots into the gravel push the bottom of the stems in.
There’s many different kinds of fish tank plants available at your local pet store or even for sale here on the internet. Here’s a list of some of the most popular aquarium plants.
