Top 10 Red Aquarium Plants Roundup: High Tech Colour Picks
Reds anchor the colour gradient of every Dutch and nature aquascape, but they only show their true intensity under demanding conditions. The top 10 red aquarium plants ranked here all need high light (50+ PAR), pressurised CO2, and steady iron supplementation to develop saturated colour. This roundup from Gensou Aquascaping at 5 Everton Park ranks each by colour intensity and difficulty. Soft Singapore tap water at GH 2-4 suits every species; nitrate management is the variable that often makes or breaks colour development.
1. Ludwigia Super Red (Ludwigia palustris “Super Red”)
Top-to-bottom blood red under 80+ PAR. The reliable high-tech red. Reaches 25-30cm. SGD 8-15 per bunch. Rotates colour from green to scarlet within three weeks of being placed under strong light. Pair with a CO2 system for full saturation.
2. Rotala Macrandra
Large rounded leaves in deep wine red. Demanding: high light, CO2, soft water, low nitrate. 25-35cm tall. SGD 12-22 per bunch. Magnesium and iron deficiency shows fast as leaf curling. Considered the trophy red stem.
3. Alternanthera Reineckii
Burgundy-purple stems available in Mini, Cardinalis and Rosanervig variants. SGD 8-15 per bunch. The mid-range red for keepers without ADA-grade lighting. Tolerates 40-60 PAR.
4. Ludwigia Palustris (Standard)
Smaller-leaved cousin of Super Red. Olive green tops, copper-red undersides under medium light. SGD 6-12 per bunch. Reaches 20-25cm. Forgiving in low-tech setups.
5. Rotala Wallichii
Needle-thin foliage in pink-magenta whorls. High light, CO2, GH 2-4 mandatory. SGD 10-18 per bunch. Singapore PUB tap suits it perfectly — soft water is the harder variable to provide elsewhere.
6. Proserpinaca Palustris (Cuba)
Toothed olive-to-orange leaves. High light, CO2 helpful. SGD 12-20 per bunch. Develops saw-tooth red leaves under strong light; under low light it stays green and spear-shaped. Dramatic transformation reliably observable in two weeks.
7. Ammania Gracilis
Larger-leaved red in pinkish-orange. 30-40cm tall. SGD 10-18 per bunch. Demanding on iron — supplement weekly with a chelated iron product from the aquarium plant fertiliser range. Tendency to discard lower leaves under poor lighting.
8. Myriophyllum Mattogrossense Red
Feathery whorls in golden-red gradient under high light. 25-35cm tall. SGD 10-18 per bunch. Sensitive to liquid carbon overdoses — introduce slowly. Adds fine texture variation to dense red plantings.
9. Rotala Butterfly
Compact rotala with butterfly-shaped opposing leaves in pink-orange. SGD 12-20 per bunch. 15-20cm tall. Newer variety that holds compact form better than rotundifolia under high light.
10. Ludwigia Rubin (Ludwigia repens “Rubin”)
Cherry-red leaves under high light, copper-orange in mid-range conditions. SGD 8-15 per bunch. Reaches 25-30cm. The most forgiving red on this list — develops noticeable colour even in 40 PAR no-CO2 tanks, though full intensity requires high-tech setup.
