Beginner Aquarium Plants Guide: Low-Maintenance UK Species

What Is the Java Fern and Anubias: The Indestructible Duo?

Java Fern (Microsorum pteropus) and Anubias species are the two most recommended plants for beginners because they are extraordinarily resilient, tolerate low light, grow in virtually any water parameters, and do not require planting in substrate. Both species grow from a rhizome (a thick horizontal stem) that must be attached to hardscape (wood, rock, or decorations) rather than buried in gravel or sand. Burying the rhizome causes it to rot and die.

Attach Java Fern and Anubias to driftwood or rocks using cotton thread, fishing line, or superglue gel (cyanoacrylate, which is aquarium-safe once dried). Within weeks, the plants develop holdfast roots that grip the hardscape permanently, and the thread can be removed or will dissolve naturally. Both species grow slowly, which means less trimming and maintenance. Java Fern produces new plantlets from its leaves, while Anubias can be divided by cutting the rhizome.

Several varieties of both species are available in UK aquatic shops. Java Fern Windelov has attractively split leaf tips, Java Fern Narrow Leaf has slender leaves ideal for smaller tanks, and Java Fern Trident has delicate, forked leaves. Anubias Nana is the most popular small variety, Anubias Barteri is a larger species, and Anubias Nana Petite is a miniature form perfect for nano tanks. Prices typically range from 4-8 pounds per pot. Our fish tank decoration guide covers aquascaping with these plants.

What Are the Amazon Sword and Rosette Plants?

Amazon Sword (Echinodorus species) is a classic aquarium plant that grows large, lush, and impressive with minimal effort. It is a root-feeding plant that should be planted in substrate (gravel or aquarium soil) with root tabs providing nutrients. A single Amazon Sword can grow 30-50 cm tall with broad, sword-shaped leaves, making it an excellent centrepiece or background plant for tanks of 60 litres or more.

Amazon Swords tolerate a wide range of conditions but perform best with moderate lighting and nutrient-rich substrate. In standard gravel, supplement with root tab fertilisers pushed into the substrate near the root base every 2-3 months. The plant reproduces by sending out runners with daughter plants that can be detached and replanted once they develop their own root system. Remove any leaves that develop holes or turn yellow to maintain plant health.

Cryptocoryne species are another excellent rosette plant family for beginners. Cryptocoryne Wendtii (available in green, brown, and red varieties) is the most popular, growing to 10-20 cm and tolerating low to moderate light. Cryptocorynes are notorious for “crypt melt” when first planted, where existing leaves die back. This is a normal adjustment response; the roots remain alive and new leaves suited to the aquarium conditions will grow within 2-4 weeks. Our aquarium lighting guide covers light requirements for planted tanks.

What Are the Background and Tall-Growing Plants?

Vallisneria (commonly called Val or eelgrass) is the premier background plant for beginners. Its long, grass-like leaves grow from the substrate to the water surface and beyond, creating a dramatic green curtain effect at the back of the aquarium. Vallisneria Spiralis is the most commonly available species in UK shops, while Vallisneria Gigantea has wider leaves for larger tanks.

Vallisneria is a prolific spreader, sending out runners through the substrate that produce daughter plants at regular intervals. A single plant can colonise the entire back of a tank within a few months, which is either a benefit (free plants, full background) or a management task (regular thinning of excess runners). It tolerates a wide range of lighting and does not require CO2, though it appreciates a liquid fertiliser dose weekly.

Hornwort (Ceratophyllum demersum) is another excellent tall-growing option that can be planted in substrate or left floating. It grows rapidly, absorbs nitrate efficiently, and provides dense cover for fry and shy fish. Elodea (Egeria densa) serves a similar role but is listed as an invasive species in parts of the UK, so it should never be released into natural waterways. Both species may need regular trimming as they grow quickly. See our algae control guide for how plants help prevent algae growth.

What Are the Mosses and Carpeting Plants for Beginners?

Java Moss (Taxiphyllum barbieri) is the most popular aquarium moss and one of the easiest plants to grow. It attaches to any surface (wood, rock, mesh, decorations) and forms dense green cushions that provide excellent shelter for fry, shrimp, and small fish. Attach it using cotton thread or superglue, and it will eventually grip the surface with its own rhizoids. Trim regularly to maintain shape and prevent the interior from dying due to lack of light penetration.

Christmas Moss (Vesicularia montagnei) has a more structured, triangular growth pattern that many aquascapers find more attractive than Java Moss. Flame Moss (Taxiphyllum sp.) grows vertically in a flame-like pattern, creating a unique visual effect on driftwood. All mosses thrive in low to moderate light without CO2, making them ideal beginner plants.

True carpeting plants (Dwarf Baby Tears, Monte Carlo, Glossostigma) generally require high light and CO2 injection, placing them outside the beginner category. However, a carpeting effect can be achieved without CO2 using Marsilea Hirsuta (a four-leaf clover plant that grows slowly but spreads along the substrate) or by densely planting Cryptocoryne Parva, the smallest Crypt species. Our fish tank setup guide covers substrate choices for planted tanks.

What Are the Planting, Fertilising, and Maintaining Beginner Plants?

Substrate choice matters for rooted plants. Nutrient-rich aquarium soils (Tropica Aquarium Soil, Fluval Stratum) provide the best growing conditions but can alter water chemistry and are more expensive. Standard gravel works for most beginner plants when supplemented with root tab fertilisers. Sand is suitable but compacts more tightly, so use root tabs and avoid very fine sand that restricts root growth.

Fertilisation for beginner planted tanks is straightforward. A weekly dose of liquid all-in-one fertiliser (Tropica Premium Nutrition, Seachem Flourish, or Easy Life ProFito) provides the micronutrients and trace elements that plants need but are not supplied by fish waste alone. Root-feeding plants (Amazon Sword, Cryptocoryne, Vallisneria) benefit additionally from root tab fertilisers pushed into the substrate near their base every 2-3 months.

Maintenance involves removing dead or yellowing leaves, trimming plants that outgrow their space, thinning runners that spread too aggressively, and cleaning algae from slow-growing leaves (Anubias is particularly prone to algae on its leaves due to slow growth). A healthy planted tank typically requires 15-20 minutes of plant maintenance per week alongside regular water changes. The reward is a natural, balanced ecosystem that is healthier for your fish and more beautiful to observe. Our maintenance schedule integrates plant care into the weekly routine.
