A fern moss terrarium is a great way to introduce exotic ferns into your planted aquarium. Ferns are very hardy perennials that grow throughout the world. They do require a fair amount of care and attention however and are not recommended for inexperienced or novice aquarium keepers. The best terrarium plants for this are those that are hardy and can withstand high temperatures and light levels.
There are several different types of fern that you can grow in a terrarium. One type of fern that you might like to consider is the false fern, which has beautiful flowers on its leaves. This plant is very easy to care for and is ideal for low light aquariums. Some other types of ferns that can be used in a terrarium are the rock fern, the featherstone fern and the hairy palm fern.
If you have never had a terrarium before you may be wondering what all of the fuss is about. There are actually three primary components to a terrarium including a base, a tank, and aquatic plants in the form of Ferns or Fern spores. All three items should be present during a terrarium setup. The reason why you would want to use a terrarium is so that you can provide your fish with a place to hide from potential predators. Terrestrial plants also add a natural source of food for your fish as well as being aesthetically pleasing to the eye.
There are a number of ways to set up your terrarium. One way to set up your terrarium is called “planted” or “air”. The plants are placed directly on top of a piece of wood or other sturdy surface. This method is quite effective because the plants will stay in one place, the air circulation in the terrarium will circulate nicely, and any insects will not be able to jump from plant to plant. It can be a bit messy though if you decide to use this method.
The next method involves using media. Media is used primarily to help keep the Ferns from drifting away from their roots. This includes putting gravel on top of the terrarium to keep it upright, placing newspaper underneath to catch any falling leaves, and putting a sheet of plastic over the top. Any loose soil can be rolled up into the media. This method is good if your terrarium is going to be exposed to water, as water will tend to get caught up in some of the smaller areas of the terrarium.
Many people choose to use substrates. A substrate is simply a layer of soil mixed with a liquid. Many people like to use bark, but I find that a cork capsule filled with the proper ratio of moisture and soil is the best. Adding a little bit of gravel to the tops of the terrarium can also help to keep the Ferns from floating away.
If you do decide to use substrates in your Fern molds terrarium, I would recommend making sure that you only use about half of the amount that you think is needed. Simply put, when you add more substrate to your terrarium, you will actually be increasing the amount of water that can collect in the soil. This will make your terrarium susceptible to being over-watered, which can kill some of your delicate plants.
The final option that you have is to use something like Aquaseal. Aquaseal is designed specifically to absorb excess water. Because of its special design, it does not allow the water to evaporate. This will prevent your Ferns from drying out. I personally have used Aquaseal and can highly recommend it.
