Potted Ludwigia Repens Aquarium Plant

  • $3.99


Ludwigia repens is a species of flowering plant in the evening primrose known by the common name creeping primrose-willow. It is native to parts of the Americas and it has the potential to spread easily and become naturalized  in many areas. It is known as an aquatic weed in some regions. It is also cultivated as an aquarium plant. This is a mat-forming perennial herb with a creeping stem up to 30 centimeters long, rooting at nodes which come in contact with wet substrate. The leaves are oppositely arranged and up to 4 or 5 centimeters long. The flower has four yellow colored petals no more than 3 millimeters long nested on a base of four pointed sepals which may be slightly longer.

The amphibious Red Ludwigia can be identified by its spade-shaped leaves with dark green tops and reddish bottoms. Sometimes called "Water Primrose," the plant needs moderate or substantial lighting and a vitamin-enriched substrate for its leaves to thrive. Red Ludwigia is ideally used in an aquarium's middle ground, though it can also serve as a background plant in smaller aquariums.

Things to remember:

Water temperature:

Aquatic plants require a tropical community aquarium with water temperaturesranging between 72-78º F (22-26º C). Use an aquarium heater to maintainwater temperature.

Adding plants:

Whether you're just starting your aquarium or introducing new plants into your tank, make sure to add only one or two plants at a time.

Lighting:

Most tropical plants require sunlight each day, year round. The duration and consistency are essential for plants to thrive. Natural aquariums must be equipped with the means to provide 12 hours of simulated sunlight each day.

Plant fertilizer:

Fertilizer should only be added according to the dosage instructions on the label, and only when needed (as in the case of a water change). Plants will grow best if fertilized moderately and regularly after water changes rather than given larger quantities of fertilizer on a less-regular basis.

Fish and plants:

Small schooling fish are highly recommended for a natural planted aquarium; larger fish often uproot plants. The adult size and eating habitats of a fish should always be taken into consideration.

Water changes:

Test water weekly to assess water quality. It is recommended that 10% of youraquarium water be changed per week. At the very least, 25% of your aquariumwater should be changed per month. For optimal health, regular water changes not only prevent the undesirable accumulation of excess nutrients, but also remove excess nitrates and waste products of the fish and plants.

Aquarium placement:

Place your aquarium in a low-traffic area, away from direct sunlight and drafts.

Planting your natural aquarium:

Foreground plants: Usually stay very short and help fill in the front part of the aquarium.

Middle ground plants: These plants grow anywhere form 4-10 inches tall.

Background plants: These are the fastest-growing and tallest plants.

Things to watch for:

  • Poor growth
  • Brown spots on leaves
  • Plants appear weak, pale green to yellow, stems have few leaves
  • Plants cease to grow and die off
  • Stem plants have long internodes and small leaves

If you notice any of the signs described above, check your aquariumwater quality and consult an in-store Aquatics Specialist.
