Tiger Lotus is one of the most decorative aquarium plants, valued for its beautiful variegated submerged leaves. While it can produce floating leaves on the water surface, it’s the underwater foliage with characteristic tiger-like patterns that makes this plant particularly attractive to aquarists.
Scientific name: Nymphaea lotus
Description of Tiger Lotus
This plant is also called red tiger lotus, spotted water lily, or simply Nymphaea lotus. In my experience, tiger lotus is a relatively large plant whose leaves can reach 15-60 centimeters in length. I recommend placing it in spacious aquariums of at least 150-200 liters, where it can fully display its decorative potential.
The leaves have a distinctive coloration—green or reddish with randomly distributed spots and stripes resembling tiger markings. There are red and green forms of tiger lotus, with the red variety being especially striking under bright lighting.
Flowering
Tiger lotus typically blooms during warm months—from spring through summer. The flower stalk rises above the water, and a large white flower opens with lanceolate petals of snow-white color and yellow-lemon stamens. The flower opens at night and closes with the first rays of sun. Flowering continues for about three days, after which the flower descends underwater.
If pollination occurs—either naturally or artificially using a soft brush—a fruit develops over approximately 40 days. After ripening, it bursts, releasing up to a thousand tiny seeds about 1.5 mm long and 1 mm wide. Seeds don’t germinate all at once—some may remain dormant for up to eighteen months.

Temperature Requirements
Tiger lotus thrives in tropical aquariums with water temperature of 24-28°C. Below 22°C, the plant significantly slows its growth and won’t flower. In my experience, prolonged cooling to 20°C can lead to serious weakening or even death of the plant.
Water Parameters
For full development with floating leaf formation, water should be soft—no more than 4-6°. In harder water, the plant begins to bush out, forming numerous basal shoots without producing floating leaves, while submerged leaves become smaller.
Due to its ability to adapt to conditions, reinforced through prolonged cultivation, domesticated plants tolerate dGH up to 10-16° and pH up to 7.2-7.7. However, for best growth I recommend maintaining optimal parameters.
An interesting feature: tiger lotus prefers aged water rich in humic acids, so frequent water changes aren’t necessary. Replacing 20-25% of the volume every 2-3 weeks is sufficient.
Lighting
Lighting should be bright, with intensity of at least 0.6 W/L. For flowering, a photoperiod of 10-12 hours is desirable. With insufficient lighting, leaf coloration fades, petioles stretch, and the plant loses its decorative appeal. In my experience, direct sunlight for several hours daily has a beneficial effect on coloration and overall plant condition.
Substrate and Fertilization
Substrate can be almost anything—small pebbles, coarse river sand, fine gravel. Layer thickness should be at least 5-7 cm. When planting, it’s advisable to add fertilizer to the planting hole—a clay ball or special tablet for aquarium plants.
As supplemental feeding, root tabs are recommended under the plant’s roots. During active growth, mineral supplementation is beneficial—adding comprehensive fertilizers with microelements once every 1-2 weeks. CO2 injection accelerates growth and improves tiger lotus appearance, though it’s not mandatory.
For successful cultivation of demanding species, balanced nutrition is especially important—similar principles apply to plants like Echinodorus vesuvius and other large decorative species.
Propagation Methods
Tiger lotus reproduces through several methods:
Vegetative Propagation
The simplest method is dividing basal shoots that form abundantly around a strong, well-developed mother plant. Young plants are carefully separated and planted in new locations.
Additionally, small tubers 1-1.5 cm in diameter form on the roots. Each such tuber can give rise to a new complete plant. This is especially convenient when you need several specimens from one bush.
Seed Propagation
Large white flowers are easily artificially pollinated with a fine-bristled squirrel brush to obtain sufficient seeds. Seeds are planted in shallow containers with a thin layer of substrate and small amount of water, maintaining temperature around 27°C and bright lighting. Seedlings emerge unevenly—some seeds may germinate within weeks, others after months.
Care Considerations
Seasonal Growth
The plant is seasonal, with development almost ceasing during winter. In cold months, tiger lotus slows growth and produces virtually no floating leaves, maintaining only submerged foliage. During this period, temperature can be lowered to 20-22°C. In March, replanting the plant is beneficial to stimulate growth.
Managing Surface Leaves
After flowering and fruit maturation, tiger lotus tends to actively produce aerial leaves that float on the water surface. Sometimes these leaves can cover the entire surface, impairing gas exchange and shading other plants.
In such cases, floating leaves can be carefully trimmed with scissors, cutting the petiole at the root. If the plant is weakened, it’s better to remove about two-thirds rather than all leaves at once. In my experience, after such pruning, tiger lotus usually forms a new rosette of submerged leaves, which are more decorative and don’t interfere with other aquarium inhabitants.
Growth Stagnation
Sometimes tiger lotus unexpectedly stops growing. The plant dislikes sudden parameter changes. However, many aquarists note that minor controlled stress—slight changes in pH, temperature, or water hardness—can stimulate renewed growth.
Adaptation to New Conditions
The plant adapts to new conditions with difficulty and often loses leaves. Don’t worry if leaves dissolve after transplanting or purchase—with an intact rhizome, tiger lotus will recover and produce new foliage adapted to your aquarium conditions.
Compatibility and Placement
Tiger lotus combines well with most aquarium inhabitants. Its large leaves create shaded areas appreciated by many fish. The plant suits aquariums with discus and other species preferring similar water parameters—high temperature and soft, slightly acidic environment.
Place tiger lotus in the midground or background, considering its size. In large aquariums, it can become an effective solitary specimen—a single accent plant. It looks impressive combined with other large-leaved species, such as Echinodorus ocelot.
Unlike fast-growing stem plants such as Elodea canadensis, tiger lotus maintains a more compact growth pattern and doesn’t require frequent trimming.
Recommendations for Beginners
Tiger lotus hardiness and relative undemanding nature allow me to recommend this plant to beginning aquarists. The only serious requirement is sufficient aquarium volume (at least 150-200 liters). Other care conditions suit most tropical inhabitants and don’t require creating special parameters.
In my experience, tiger lotus is an excellent choice for those wanting to add a large, striking plant without complex maintenance. It forgives many beginner mistakes and can grow even without CO2 and specialized fertilizers, though under optimal conditions it reveals its beauty more fully.
If your aquarium size permits—definitely get acquainted with this interesting and decorative plant.
