Anubias is an entire genus of plants, which includes several cultivars and varieties of the most common species, Anubias barteri.
Native to freshwater rivers and streams throughout tropical African regions, anubias typically attach themselves to surfaces like sunken logs, roots, or rocks along the riverbank.
Anubias can grow either emerged (with the leaves above the water line) or immersed (entirely underwater).
The plants grow from a central rhizome, and their roots mainly function to anchor the plant.
Anubias is relatively slow growing, with one new leaf every 1-4 weeks. The size of the tank and the species of anubias chosen will determine the placement of the plant.
Anubias prefers low lighting and should be given enough room to grow without being overshadowed by other plants in the aquarium.
This makes it an excellent choice for those looking to create a lush, low-light environment in their tank.
It is important to note that the common name “Anubias” refers to an entire genus of plants, not just one particular species.
Several cultivars and varieties of the most common species, Anubias barteri. Anubias is an excellent plant choice for cat owners, as it is easy to maintain and won’t cause any harm to cats that try to nibble on it.
It can also add a beautiful, lush look to your tank while providing plenty of hiding spots for fish and other aquatic creatures.
3) Java Fern
Java Fern is one of the most popular plants in planted aquariums. It is appreciated for its slow growth, unique leaf structure, and reproduction method.
Java Fern can tolerate most lighting conditions and many environments, from soft acidic water to alkaline conditions and even brackish tanks.
When planting Java Fern, you can float it in the tank, bury the roots in gravel, tie it onto a piece of wood, rock, or other décor, or use super glue gel.
Make sure not to bury the plant’s rhizome, as it needs to be exposed to light for photosynthesis.
One of the main advantages of this plant is that it does not require a substrate, making it ideal for bare-bottom tanks.
Java Fern will do best with a 6700k spectrum bulb but can survive with any range from low to medium-high light.
Surprisingly, Java Fern can live off very little light, even if forgotten in a bucket for several weeks.
Java Fern is a very low-maintenance plant that will spread slowly, giving your aquarium a unique look.
The plant is safe for cats, so there’s no need to worry if you have a curious kitty at home. With proper care and a little love, Java Fern will reward you with beautiful greenery for years.
4) Christmas Moss
Christmas Moss, or Vesicularia Montagnei, is a widely used plant in aquarium husbandry.
Named for its branches that hang down, overlapping each other to form the shape of a Christmas Tree, this moss is native to tropical Asia and can be found in Thailand, India, Japan, and the Philippines.
Its appearance is characterized by its round or oval-shaped leaves in a rich, dark green that terminates in a sharp point.
This plant thrives best in excellent, flowing water with a wide temperature range of between 65o to 77 degrees Fahrenheit.
This moss is an attractive addition to any freshwater aquarium when correctly cared for.
Christmas Moss is also known by its scientific name, Vesicularia Montagnei, and is a member of the Hypnaceae family.
When properly cared for, this moss is an attractive addition to any freshwater aquarium and can help create a lush and inviting space for you and your feline friends to enjoy.
Hornwort is a flowering aquatic plant that is identifiable by its unique, horn-like needles. It is used in many aquariums because it can beautify, oxygenate the water, provide cover for small fish and invertebrates, and clean the water.
Scientifically known as Ceratophyllum demersum, this aquatic plant is native to North America but has since spread to other continents.
Hornwort can be found in ponds, lakes, ditches, and quiet streams.
Hornwort thrives in slow-moving water- such as streams, marshes, ditches, lakes, ponds, and other wetlands/humid areas.
It is an undemanding plant that is resilient and cost-effective. Hornwort is an ideal aquarium plant for pet owners with cats, as it is non-toxic and can provide a safe and stimulating environment for both the fish and the cats.
Its unique, horn-like needles provide an exciting place for the cats to explore and relax.
Hornwort belongs to the Kingdom Plantae, Clade Tracheophytes, Clade Angiosperms, Order Ceratophyllales, Family Ceratophyllaceae, Genus Ceratophyllum, and Species Ceratophyllum demersum.
It is native to North America, though it has since spread to other continents.
It is found in ponds, lakes, ditches, and quiet streams in slow-moving water such as streams, marshes, ditches, lakes, ponds, and other wetlands/humid areas.
6) Water Sprite
The Water Sprite (Ceratopteris thalictroides) is a floating aquatic fern often used in aquariums to provide cover and shade for fish.
Native to tropical regions of the Americas, the Water Sprite has become popular in home aquariums as an oxygenator and attractive addition.
The Water Sprite has bright green feathery leaves with frilly edges and can grow up to 10 inches long.
They are best kept near the top of the tank, so it’s important to ensure you have adequate lighting for this plant.
You can expect the Water Sprite to spread quickly, so ensure there is plenty of room for it to grow.
Good tank mates for the Water Sprite include schooling fish such as tetras, guppies, and rasboras.
Fish to avoid include larger predatory species like angelfish, which may attempt to eat the delicate leaves.
Water Sprite should be fed a combination of liquid and solid fertilizers every few weeks. It’s also important to provide supplemental carbon dioxide to the tank since it needs plenty of CO2 to remain healthy and vibrant.
When caring for the Water Sprite, it’s crucial to maintain a planted tank environment with a pH of 6.5-7.5, GH between 3-8, and KH between 1-4.
It’s also essential to provide adequate filtration, oxygenation, and moderate water flow.
To maintain these parameters, weekly water changes should be performed, and dissolved organics should be tested regularly with an aquarium test kit.
Additionally, the tank should be monitored for signs of ill health, such as yellowing of leaves or discoloration of stems.
When setting up an aquarium for the Water Sprite, start with a layer of substrate topped with aquarium gravel or sand and fill it with dechlorinated water at the desired temperature range.
Then, add low-light plants and decorations to create hiding places for the Water Sprite.
To propagate the Water Sprite, simply snip off pieces of the stem with healthy new growth and replant them in another part of the aquarium.
With good care, you can expect your Water Sprite to thrive in your aquarium.
