Anacharis, a hardy and easily kept plant, is probably the most commonly kept aquarium plant.
Anacharis, Brazilian Waterweed, and Elodea are all common names used to for this species, Egeria densa. While this species is most suitable for a tropical aquarium, it can also be kept in cooler water. These same common names are also applied to the American or Canadian waterweed species of the Elodea genus, which are very similar. Elodea species are suitable for cool aquariums or ponds however, rather than tropical environments. To be certain of which 'Anacharis' you are obtaining, be sure to check its scientific name.
Anacharis will root if the shoots are buried in the gravel, however they can be kept either as floating plants or as rooted plants. They grow very well in ponds and goldfish tanks and will survive in cold water. They are great beginner plants because they adapt very easily, grow quickly, and are easily propagated. They are also good oxygenators. The stems will grow up to 50 cm (20 in) or more, so they usually need to be kept trimmed. Brazilian Pennywort

Brazilian Pennywort is an exotic plant with a very funky look, a most Interesting plant to add to an aquarium!
The Brazilian Pennywort is a great plant for midground to background or surface decoration. It has thin spindly stems and lily pad shaped leaves. At any given moment, plants will sport leaves ranging in size from a dime to a half dollar.
At each leaf joint the plant sends out white roots. Very healthy specimens will send up a wispy white bloom that will open near the surface. Some aquarists choose to not root Brazilian Pennywort in the substrate, instead allowing it to grow horizontally on the surface.
Brazilian pennywort can grow a few inches per week in just about any tank. However underfed plants will be slow growing, weak, and unattractive. A good fertilizer regimen would include both a root fertilizer (usually mixed in with the substrate) and a leaf absorbed fertilizer (usually added to the water). Co2 fertilization also helps this plant a lot. Brazilian Pennywort will be nibbled on by snails and some fish, but healthy specimens recover easily. Broadleaf Ludwigia

It is best to usually group several plants together, with small spaces between each one.
Although the Fountain Plant is a fairly hardy plant and can survive in most conditions, the water should be regularly checked to help it thrive. It needs a pH between 6.5 and 7.5, and minimal light to keep it growing and looking healthy. Make sure to perform regular water changes and fertilize regularly after each change. The bottom substrate should be nutrient-rich. Propagation of the Fountain Plant is done by planting cuttings from the side sprouts of the main plant. Hornwort
Ceratophylum demersum [You must be registered and logged in to see this image.]
Hornwort is a good plant for aquariums with plant eating fish, since the hard leaves do not taste so good!
A rootless plant, Hornwort can be kept floating at the top of the aquarium or buried in the gravel to suit your taste. If you bury Hornwort in the substrate, the Hornwort stems are held in the gravel by root-like organs called rhizoids. The stems will branch off to form nice thickets for fish and especially fry to retreat into. Be careful with it however, because it breaks easily and many of the pieces can become their own plants. Hornwort is an easy plant to care for since
Hornwort can be kept in many aquarium environments, such as coldwater aquariums and tropical aquariums. It is a great aquarium plant for all levels of experienced aquarists. It is also readily available at fish stores or online. Variegated Japanese Rush
Acorus gramineus [You must be registered and logged in to see this image.]
This Variegated Japanese Rush is actually not a true aquatic plant, but can survive for up to a year completely submersed in water!

Since it is not a true aquatic plant, the Variegated Japanese Rush does better in tropical aquariums where about half of each leaf is above water. It will grow in many substrates and the roots are thick and are quite capable of taking nutrients directly from the water. The Japanese Rush propagates by producing shoots from the base which will eventually spread and create their own plant. Water Milfoil
Myriophyllum Sp. [You must be registered and logged in to see this image.]
The Water Milfoil is an ideal plant for the aquarium. Though they do require good light they're not overly particular about the composition of the water and they can withstand great fluctuations in temperature.
Members of the genus Myriophyllum are popular aquarium plants and the aquatic species of Water Milfoil have found their way into hobbyists tanks for generations. It is one of the many aquarium plants sold under the name "Foxtail".
The delicately cut green or red foliage of the Water Milfoil is surprisingly hardy. This plant prefers strong light but is usually willing to compromise on this. It is an excellent plant for filling in gaps in the aquascape as it will adapt to many conditions. Water Milfoil will probably tolerate colder temperatures than any aquarium fish.
Water Milfoil can easily reach the surface of most aquariums. When it does this, snip off the top 1/3-1/2 of the plant and replant. This plant is also a must for breeding tanks as an egg site or fry refuge. Aquarium gravel is a perfectly acceptable substrate for this plant as roots are primarily anchors. Be sure to plant the stems separately to allow them to root.
The only problem that is encountered with this beauty is its tendency to trap debris. This can be easily solved by occasional gentle shakes to free debris. Alternatively, place the Water Milfoil near the suction or current of a filter. As with most plants, occasional fertilization would be appreciated.
This plant (Myriophyllum species) are on many invasive species lists, so extreme caution needs to be taken that no part of the plant is released into the environment. Water Primrose
