Red Ramshorn Snail
Planorbarius corneus
Red Rili Shrimp
Neocaridina davidi
Red Root Floater
Phyllanthus fluitans
Popular floating plant with round leaves that turn red under high light. Long, red roots dangle attractively. Excellent nutrient absorber.
Red Ruby Shrimp
Caridina logemanni
Red Swordtail
Xiphophorus hellerii
Red Tail Catfish
Phractocephalus hemioliopterus
Red Tibee Shrimp
Caridina sp. (Tibee)
Red Tiger Lotus
Nymphaea zenkeri
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.
Red Turquoise Discus
Symphysodon sp.
Red Wag Platy
Xiphophorus maculatus
Red Wine Shrimp
Caridina logemanni
Red-Bellied Piranha
Pygocentrus nattereri

Rhino Shrimp
Caridina serratirostris
Rhizoclonium
Rhizoclonium sp.
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.
Riccia
Riccia fluitans
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.
Ricefish
Oryzias woworae
Ricordea Florida
Ricordea florida
Ricordea Yuma
Ricordea yuma
Rili Red Sakura Shrimp
Neocaridina davidi
Rili Shrimp
Neocaridina davidi var. Rili
River Buttercup
Ranunculus inundatus
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.
Rock Prawn
Macrobrachium lar
Rope Fish
Erpetoichthys calabaricus
Rosanervig Hygrophila
Hygrophila polysperma
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.
Rose Moss
Taxiphyllum sp. 'Rose'
Rare moss with fronds arranged in rosette patterns resembling tiny roses. Slow-growing and delicate but creates stunning textures.
Rose Sword
Echinodorus sp. 'Rose'
Hybrid sword with pink-tinged new leaves that mature to deep green. Compact size compared to other swords. Popular centrepiece.
Rosetail Betta
Betta splendens 'Rosetail'
