Growing aquarium plants can change an ordinary fish tank into a beautiful underwater garden. There are many different types of aquarium plants, but they all have one thing in common; they have adapted to living in a water saturated environment. They thrive with their feet wet in soggy soil and many prefer to be submerged.
Growing Info and Care of Aquarium Plants
Sometimes called hydrophytes, these different types of aquarium plants offer such a variety of shape and form.It’s entirely possible you’ll want to create an underwater garden without the fish!
For the best and easiest care of aquarium plants, your tank should receive plenty of light. Like their surface-bound cousins, these plants need the energy produced through photosynthesis to survive and photosynthesis can’t occur without sunlight or an artificial substitute.
Aquarium plant how-to depends a great deal on the plants involved. When choosing varieties, look for those that share common light and nutritional requirements. For instance, in such a closed and confined environment, it would be difficult to satisfy the needs of both a bright light and minimal light plant.
Types of Plants That Can Be Used in an Aquarium
There are three main types of plants that can be used in an aquarium that we’ll be talking about here: rooted plants, bunch plants, and floating plants.
Rooted plants come in a variety of shapes and sizes. They spread from runners rather than seed. These are the plants that can be used in an aquarium garden for background plantings. Learning how to grow aquarium plants begins with these. These plants need their roots firmly planted in the gravel, but take care; for plants like this shouldn’t be planted too deeply, only to the base of the crown.
Choose two different varieties for the back corners of your tank and if it’s a large tank, choose a third for the middle. Rooted plants usually grow from 8 to 12 inches tall and although there are many available, the few offered here were chosen for their contrasting shapes and popularity.
- Eel Grass (Vallisneria): Leaves are light green ribbons. Some are corkscrewed. All bend and twist with the slightest water movement.
- Sword Plant: This bright green beauty is one of the few types of aquarium plants that should be grown in pots. Use a shallow one with soil filling the bottom half topped by gravel or sand.
- Fanwort (Cabomba): Light green, fan shaped, feathery leaves grow from central stalks. This one’s an eye-catcher.
- Elodea: Narrow leaves grow around stems that can reach 3 feet long.
Bunch plants get their names from the way they are planted, in groups or bunches. They grow rapidly and need lots of light. Bunch plants can be used in an aquarium equivalent of middle ground plants. Each individual strand should be planted in its own hole. A pair of tweezers works well as a planting instrument.
- Anacharis: Fine and feathery, it makes a great place for small fry fish to hide.
- Ambulia: Light green, fan-like leaflets circle around slender stems.
- Bacopa australis: Small round leaves. When planted closely, it looks like a miniature shrub.
Floating plants take root in water, but don’t need to be anchored to the gravel. When it comes to how to grow aquarium plants, this type only needs a source of light. The more light, the faster they grow. Beware! These rapidly growing aquarium plants can take over in no time.
- Crystalwort: Bright green and it grows in thick mats similar to moss.
- Hornwort: An oxygenating plant with whirling narrow leaves on bushy stems.
- Anacharis: The same plant as the bunch variety, but allowed to float free.
Growing aquarium plants can be both beautiful and functional. They absorb CO2 and release oxygen just as their land-bound counterparts. Nitrates accumulation can be a problem in the care of aquariums. However, aquarium plants help remove nitrates from the water. They harbor beneficial bacteria and help prevent algae growth. They also provide food for your fish.
With all the benefits of growing aquarium plants, why wouldn’t you give it a try?
NOTE: The use of native plants in a home water garden or aquarium (referred to as wild harvesting) can be risky, as most natural water features are host to a plethora of parasites. Any plants taken from a natural water source should be quarantined overnight in a strong solution of potassium permanganate to kill any parasites prior to introducing them into your pond. That being said, it is always best to obtain water garden plants from a reputable nursery.
