Origins And Habitat
The Water Sprite plant is a beautiful aquatic plant that can be found growing in and around freshwater bodies in tropical regions across the globe. Water Sprite plants occur in Northern Australia, Southeast Asia, India, East Africa, and Central America.
Ceratopteris thalictroides is an adaptable species that grows naturally in a wide range of different habitats. It can be found in fresh or stagnant, standing water, marsh habitats, or gently flowing streams and grow emersed or submersed in sunny or partially shaded positions.
What Does Water Sprite Look Like?
Water Sprite is a beautiful green species for aquascapes that looks a lot in appearance like terrestrial ferns do. This fern takes different forms depending on how it is grown in the fish tank and what kind of lighting it gets. Ceratopteris thalictroides grow from a short rhizome and their foliage varies from vibrant light to deep dark green.
Plants that are allowed to float in the fish tank will take on a more spreading, flattened appearance. This floating plant also developed a large interesting white, hanging root system.
Indian Fern plants that are grown rooted in the substrate have broad, pale leaves arranged in a rosette from a single stem. Interestingly, these plants have two different types of fine leaves. Both smaller sterile leaves and larger fertile leaves can be found on the same plant.
In very shallow aquariums, rooted Water Sprite plants will happily grow up and out of the tank water if left to grow to their full size of about 15 inches tall.
Placement And Lighting
Water sprite is a really versatile and useful species that can be used in a number of different ways in the aquascape. In the planted aquarium, the fine leaves work well to soften and break up harsh lines.
Depending on the size of your aquarium, this plant could make a great midground or background plant. In smaller aquariums, these water ferns grow tall enough as rooted specimens to create a beautiful, finely textured backdrop to your aquascape.
In larger aquariums, Water Sprite makes a great mid-ground plant that can be rooted or attached to a hardscape feature like rocks or driftwood. When grown this way with good light, Water Sprites can be very effective at hiding the base of taller stem plants in the background.
Another popular option is to allow this plant to float at the water’s surface. Bear in mind of course that floating Water Sprite plants will shade out the plants rooted below it, so be sure to grow only low light species under your floating plant.
Wherever you plant your Water Sprite, make sure it has access to at least moderate plant light to ensure vibrant color and a healthy growth rate. Rooted plants will need stronger light than floated plants because they are further from the light source.
What Are Good Water Sprite Tank Mates (Fish)?
Good Tank Mates
The Water Sprite plant is great for community tanks and will work well with most fish and invertebrate species. Nano fish species, fry, and freshwater shrimp will appreciate the safety and shelter provided by the dense foliage of this plant.
Water Sprite works equally well in species-only aquariums, as long as the freshwater fish you keep isn’t herbivore or prone to digging through the substrate.
Floating Water Sprite plants can develop really cool root systems that trap food particles and detritus in the water column, making a great place for shrimps and small fish to forage.
Fish Species To Avoid
Feeding Water Sprite (Fertilization)
Water Sprite grows fast and vigorously and does not require much feeding if rooted in a nutrient rich plant substrate. Water Sprite plants also take nutrients from the water column and are great at soaking up excess nutrients from fish food and waste. This property makes water sprite a really helpful plant for maintaining stable water parameters and preventing algae blooms.
How Much And How Often To Feed
Since Water Sprite does not necessarily need to be on a strict feeding schedule, the timing and amount of fertilizer you use will probably be more dependent on the needs of other species you might be keeping in your planted tank.
It is best to feed your plants regularly to maintain stable water parameters. Of course, it is difficult to know exactly what your plant’s nutrient requirements are without measuring so it is best to test regularly.
The best way to determine the right feeding schedule for your plants is with caution and through a process of trial and testing. Feed your plants daily or every second day and dial the amount of aquarium fertilizer in to where water parameters stay as stable as possible.
Water Sprite Care
Being a fast-growing plant, Water Sprite will need to be pruned from time to time. This is especially true under strong light and when they are taking a lot of nutrients from the water. Below is a quick video from Tropica that provides a handling and growth care video on the plant.
Use a sharp pair of aquascaping scissors to remove minor stems, rather than trimming individual leaves, because any damaged leaves or stems left attached to the plant could turn brown and rot. Be careful never to pull on a rooted Water Sprite plant or damage its primary stem as this could hurt the whole plant.
Planted Tank Parameters
Water Sprite grows well across a wide range of tank parameters. Water temperatures between 72°F and 84°F are ideal and this plant will do fine in both hard and soft water. KH values of 3-8 are ideal for this plant.
They also grow well in pretty much any pH value that you’re likely to find in an aquarium. That being said, it has been noted that water Sprite grows best in slightly acidic to neutral water.
To maintain stable water parameters in your planted fish tank, be sure to set your lighting on a timer to provide a regular and consistent light schedule. Always stock your tank appropriately and be careful not to overfeed your fish and animals.
Use a heater to maintain a stable water temperature and a filter that provides effective mechanical, chemical, and biological filtration. From time to time, you will need to rinse out your filtration media or replace the cartridges in your filter.
When rinsing out your filter media, be sure to use water that you have collected from your tank during a water change. By doing this you will avoid killing the beneficial bacteria that colonize your filter with the harsh chemicals found in most tap water.
Good water quality and tank conditions are the cornerstone of all thriving planted aquariums, and by far the most important piece of equipment for maintaining the water quality in your planted fish tank is your filter.
As good as Water Sprite is at absorbing excess nutrients in the water, you’ll still want good filtration in your aquarium to maintain a healthy system. These plants have fine, delicate leaves that do break apart from time to time. For this reason, it’s a good idea to use a filter with a prefilter sponge on its intake to prevent plant material from being sucked in.
Water Sprite is not adapted to life in fast-flowing water. Use a slow to moderate water flow in your aquarium to maintain healthy plants. In aquariums with higher flow rates, position these plants away from the outflow of the filter, or grow them behind a hardscape feature that blocks out the current.
Testing Tank Conditions
Before introducing a new plant to your fish tank, be sure to test the conditions of the water. This way you will know if the parameters in your planted tank are suitable for the species you want to grow. You will need an aquarium test kit to do this at home.
The most important water conditions for you to keep an eye on are the levels of Ammonia, Nitrites, Nitrates, pH, general hardness, and carbonate hardness in the water. It’s a good idea to get into a routine of testing your tank water conditions every week before you perform a water change.
How To Set Up Your Aquarium Tank for Water Sprite
Water Sprite is a very versatile aquatic plant and will easily adapt to most setups. If you plan on growing this as a rooted plant, provide at least 2 inches of substrate to allow your plant to develop a strong root system.
Rooted Water Sprites do not have any particular substrate requirements and can be grown in sand or gravel. In the right conditions, Water Sprite has a pretty fast growth rate in the planted tank.
This reason, coupled with the species potential height of about 15 inches, means you should grow this species in tanks of at least 10 gallons. In smaller tanks, Water Sprite can quickly take over your aquascape.
How To Propagate Water Sprite
Water Sprite is a very easy plant to propagate. Healthy, mature plants will form miniature daughter plantlets on the edges of their leaves. In time, the little Water Sprite plantlet will break free and will grow as a floating plant or attach itself to the substrate in your aquarium.
These little plantlets can be pulled from the leaves and planted in the gravel or sand once they have established their own root system. You can also attach these young plants to a hardscape feature like driftwood or rock using nylon or even super glue. The video above by gmluv illustrates the daughter leaves.
Another easy way to propagate new Water Sprite plants is to simply cut off a secondary stem from the mother plant that has healthy leaves on it. Allow this cutting to float freely in the tank and it will often develop its own healthy root system pretty quickly.
Health And Disease
Water Sprite tends to be a fast-growing, vigorous species that has few problems in the planted tank. There are always things that can go wrong, however, especially in smaller freshwater tanks. The successful aquarist is always alert to possible problems by keeping a close lookout for changes in their plants.
Signs Of Health in Water Sprite
Healthy Water Sprite plants will have vibrant green foliage and stems and a well-developed root system. Plants grown in pots should be able to grow and support themselves without bending over under their own weight.
Signs Of Ill Health
Different mineral deficiencies affect how these plants grow and often show up as characteristic discoloration and damage to the leaves of the Water Sprite. Look out for yellowing or browning of the usually green leaves. The appearance of rotting leaves and roots are also clues that signal poor health in this plant
Common Water Sprite Health Issues And Treatment
The most important needs for all aquarium plants are light, nutrients, and carbon dioxide. If you have too much, or not enough of any of these things, you could start to pick up problems with your plants. Fortunately, Water Sprite is a hardy plant that isn’t too picky about aquarium parameters.
Nevertheless, there are a few important points to remember about caring for your plants. A common problem when growing these plants in the substrate is not providing enough light and planting the roots too deeply. The crown of the plant should always be above the level of the substrate.
Another common problem with aquarium plants is an excess of nutrients like phosphates in the water. This can cause a build-up of algae in the tank and on your plants. To prevent this, make sure not to overfeed your fish and get into the habit of doing partial water changes on a weekly basis.
Plant eating snails can really take their toll on this plant. If you do keep snails, be sure to keep them well-fed for your best chance at protecting your plant. Snails and other pests are often introduced to your aquarium accidentally on new plants.
The best way to prevent this is to give new plants a good wash and a dip before introducing them to your aquascape. Start by removing any dead or unhealthy-looking leaves from the plant with a sharp pair of scissors. Inspect the plant for any snails and remove them.
Dipping your Water Sprite plants briefly in a very mild solution of bleach (20 parts water to 1 part bleach) is a great way of killing off parasites and unwanted organisms before introducing them to your aquarium. Plants should be dipped for a period of not more than 2 minutes and then washed and rinsed thoroughly before planting out.
Where To Buy Water Sprite
These plants can often be found at local aquarium stores or bought from an online fish store. Personally, my recommendation is to purchase from Buceplant if purchasing online. They also still Tropica tissue grown aquarium plants, which is a great way to prevent introducing pests into your aquarium.
