Flora & Fauna

The red tiger lotus produces large, dramatic maroon-red leaves with speckled patterns. Without high light and CO2 it will send leaves to the surface; regular trimming of surface leaves encourages bushy underwater growth. An impressive centrepiece plant for larger tanks.

Striking loach with bold reticulated patterning and a flattened body adapted for fast-flowing streams. Needs high oxygen, strong flow, and cool water. A showstopper in a hillstream biotope.

Thin, cotton-like green threads that form loose, easily detached clumps — often confused with hair algae but coarser and more tangled. Tends to form clumps rather than sheets. Usually caused by excess ammonia or organics in new tanks. Amano shrimp and Florida Flagfish handle it well.

A floating liverwort made famous by Takashi Amano, who pioneered the technique of tying Riccia to rocks and driftwood using hairnets to create lush, bright green carpet-like surfaces. Left floating, it forms a thick mat at the water surface that provides excellent cover for fry and shrimp. When submerged and attached, it releases oxygen bubbles in a process called pearling, creating a spectacular visual effect. It is not a true moss but behaves similarly and is essential in the competition aquascaping world.

Limnophila aromatica is a stunning stem plant with leaves that shift from green to vibrant purple-red under high light and good iron supplementation. Used extensively in Dutch-style aquascaping, it provides brilliant colour contrast in the background.

Rili Shrimp are a selectively bred Neocaridina davidi morph characterised by a two-tone pattern — a coloured head and tail section (typically red, orange, or blue) separated by a transparent or translucent mid-body section. This 'broken' coloration pattern is unique among neocaridina morphs and makes them visually striking in planted tanks. Care and breeding requirements are identical to standard red cherry shrimp.

Beautiful foreground or midground plant with distinctive clover-like leaves. Grows in a compact mound. Prefers slightly cooler water and good flow. One of the most unique-looking aquascaping plants.

Prehistoric-looking eel-like fish with a series of dorsal finlets. Peaceful with fish too large to swallow. Nocturnal. Can breathe air and will escape through any gap.

A stunning variegated cultivar of H. polysperma with white to pink venation against a light green or pinkish leaf. The coloration intensifies under bright light. Despite its exotic appearance it is just as easy as the parent species and grows quickly. Invasive in outdoor ponds in some US states.

The Rosetail Betta is an extreme variation of the Halfmoon with excessive branching of fin rays that causes the tail to ruffle and overlap, resembling rose petals. While visually spectacular, the over-developed fins are heavy and fragile, making the fish a weaker swimmer and more susceptible to fin rot, tearing, and spinal curvature. Best kept in very clean, still water and considered a display specimen.

Rosy barbs are large, hardy barbs with males turning a vivid pink-red during breeding. They are cold-tolerant, active, and peaceful in larger groups, though they may nip fins of long-finned fish. An excellent choice for cooler community aquariums.

The rosy tetra has a lovely soft pink to rosy body with a black and white dorsal fin and red-tipped fins that intensify with maturity and condition. Males develop a tall, flag-like dorsal fin. It is an elegant, peaceful fish that is slightly rarer in the hobby than it deserves to be, and looks beautiful in soft-water planted tanks.

Compact Rotala with thick stems and rounded leaves that blush deep red under intense light. Rarely grows tall — ideal for creating low, dense red accent patches in aquascapes.

One of the most intensely coloured Rotala varieties available, producing deep blood-red to crimson stems and leaves that stand out dramatically in any scape. Requires the highest light levels and CO₂ of any commonly kept Rotala, along with careful nutrient management. Under suboptimal conditions the colour fades to dull orange or pink. Grown well, it creates an arresting, almost unreal red that elevates competition-level scapes.

Rotala H'ra is a popular cultivar producing small, narrow leaves that shift from green at their bases to vivid orange-red at the tips under high light, creating a stunning gradient effect in background plantings. It is less demanding than R. macrandra but rewards CO2 injection and iron dosing with exceptional coloration. Its fine texture and warm orange tones make it one of the most sought-after rotala varieties in competitive aquascaping.

Rotala Indica is an easy-going stem plant with small, oval leaves that display a pleasing pink to light-red coloration on their undersides even under moderate light — making it one of the few rotala species that beginners can achieve colour from without high-intensity lighting. It grows upright with a delicate, feathery texture and is often used as a softer alternative to R. rotundifolia in low-tech setups.

A miniaturised form of the famously demanding Giant Red Rotala, producing smaller, narrower leaves but retaining the same intense red-pink colouration when kept in optimal conditions. Requires high light, CO₂, and balanced macro and micro nutrients — particularly iron — to achieve its best colour. Grows slower than the standard species but is equally sensitive to nutrient deficiencies, which show as pale or washed-out leaves. Best kept by experienced planted tank hobbyists.

A feathery, needle-leaved Rotala from Brazil producing hair-fine, almost pine-needle-like leaves in green-orange to reddish tones. The extremely fine leaf texture creates a soft, cloud-like effect in the midground or background that is highly distinctive in competition aquascaping. Demands high light, CO₂, and soft, acidic water to thrive and colour up. One of the most visually unique stem plants in the hobby — a collectors' favourite.

A delicate stem plant with small, narrow leaves that form feathery, bright green whorls. Under high light and CO2 it develops a slight pinkish tint at the growing tips. It grows vigorously and is a great mid-to-background filler, tolerating a wide range of conditions better than most Rotala species.

Rotala rotundifolia is a classic stem plant for the background and upper midground of aquascapes, producing pink to reddish tones under high light and elevated CO2. Regular pruning encourages bushy side-shoot growth. Under low light the stems grow leggy and remain green.

A compact Rotala with narrow, lance-shaped leaves that turn a warm orange-red under good light and CO₂. Slower and more compact than R. rotundifolia, making it easier to maintain as a neat midground or background plant without constant trimming. The red-orange colouration develops even at moderate light levels with CO₂, making it more accessible than demanding species like R. macrandra. A versatile choice for adding red tones to mid-sized scapes.

Rotala sp. 'Green' is a popular, fast-growing, bright green stem plant with small, oval leaves. Unlike the pinkish tones of R. rotundifolia, it stays consistently lime-green even under high light, providing excellent contrast with red-leaved plants. Undemanding and fast, it is a reliable background filler for any planted tank.

One of the most sought-after Rotala species in competitive aquascaping. Produces fine, needle-like leaves and deep pink-to-red colouring. Requires pristine water, high light, CO2, and regular trimming to maintain shape.

Compact stem plant with small, rounded bright-green leaves. Forms a bushy, dense growth habit that holds shape well without constant trimming. Excellent for filling midground gaps in planted aquascapes.

Royal plecos have striking dark striping on a grey-brown body and spoon-shaped teeth adapted for rasping wood. Driftwood is an essential part of their diet and tank décor. They grow large and require spacious tanks with powerful filtration.

Named for its distinctive red nose and black-and-white striped tail, the rummy nose tetra is a stunning schooling fish that forms tight, coordinated shoals. It is more sensitive to water quality than the neon tetra and requires soft, warm, acidic conditions to look and behave at its best. The intensity of the red colouration serves as a reliable water quality indicator.

One of the three 'dwarf' corydoras species, C. habrosus reaches just 3 cm and has a distinctive row of dark blotches along its flanks. It is more active in the midwater than most corydoras and is ideal for nano planted tanks. Groups of 10+ will show confident, exploratory behaviour and make excellent companions for small shrimp.

Vividly coloured medium cichlid with yellow and turquoise markings. Aggressive, especially when breeding. Hardy and tolerant of a range of water conditions.

Salvinia is a fast-growing floating fern that creates dense surface cover. Its tiny textured leaves repel water, forming a green carpet on the surface. Excellent for nutrient export and providing shade for light-sensitive plants and fish below.

Graceful, slender fish with a translucent body and vivid red snout and tail on males. Endemic to Inle Lake — prefers cooler, harder water than most aquascaping fish. Stunning in large groups.

Jewel of nano tanks — males are deep red with vivid blue-edged scales. Only 0.8 inches. Refuses dry food for most keepers; needs live or frozen micro prey. Worth every effort.

Schwartzi corydoras has a distinctive pattern of dark spots and a prominent black stripe through the eye. It is an active, peaceful schooling fish that spends most of its time foraging along the bottom. Well suited to soft, acidic planted tanks.

Ancient, armour-plated fish that walks along the bottom on its fins. Breathes air using a primitive lung. Peaceful with fish too large to swallow. Fascinating species.

Serpae tetras are vivid red fish with a distinctive black comma-shaped shoulder mark. They are hardy and bold, but known to be fin-nippers especially in small groups — keep 10 or more to redirect aggression within the school.

Large, deep-bodied cichlid with a friendly temperament for its size. Comes in green, gold, and red colour variants. Often bonds strongly with its keeper and will hand-feed.
