Ammannia pedicellata, historically traded as Nesaea pedicellata, is a striking and robust stem plant known for its thick, vibrantly colored stems and contrasting foliage. It can be somewhat demanding, requiring high light and ample nutrients to prevent the lower leaves from blackening or shedding.
Red Ammannia At a Glance
Red Ammannia Care and Setup
Layout Fit
Red Ammannia usually works best from the midground into the background and needs enough room to mature at about 45 cm tall and 15 cm wide.
Water Window
Aim for freshwater conditions with a steady current, plus 22 to 28 °C, pH 6 to 7.5, and 2 to 12 dGH.
Upkeep Rhythm
Expect moderate growth with moderate maintenance. It usually stays easy to manage between normal maintenance sessions.
Red Ammannia Care Guide Summary
The Red Ammannia is a stem plant that usually works best from the midground into the background. Give it room to reach about 45 cm tall and 15 cm wide, so the mature plant still fits the layout. It tends to look its best when the light, feeding, and trimming routine stay predictable from week to week. In day-to-day care, it responds best to high light, freshwater conditions, and a steady current. It is noticeably easier to keep attractive and stable with added CO2. Keep this species within a comfortable range of 22 to 28 °C, pH 6 to 7.5, and 2 to 12 dGH.
Red Ammannia Planting, Feeding & Maintenance
The Red Ammannia does best when the setup matches the way it naturally grows. Plant it with enough room for the crown and new roots to establish cleanly. It can use both the root zone and the water column, so a balanced fertilization routine is usually the safest approach. A nutrient-rich substrate helps it settle faster and usually supports fuller growth. Keep the routine steady: high light and high nutrient demand usually give better results than big swings from week to week. This plant can also adapt to emersed growth, which is useful for growers who propagate outside the display tank.

Red Ammannia Compatibility
Use these signals as quick context, not hard rules. They help you judge how well Red Ammannia is likely to stay in place, tolerate curious fish, and contribute real cover in a mixed planted tank.
Aquarium Benefits
The Red Ammannia can work very well in a mixed tank, but its value depends on how well it handles fish pressure and how much usable cover it really provides. It is less likely to be chewed by curious fish, and its standard leaves usually help it hold up in calm community tanks. Its anchoring strength is limited early on, so avoid pairing it with persistent diggers or boisterous substrate movers. It adds some usable cover without turning the layout into a dense thicket. It casts a moderate amount of shade, which is helpful when you want softer pockets of cover. Aquarists also lean on it for breaking up sight lines and shelter for fry, not just for appearance.
Red Ammannia Propagation
This species is usually propagated by stem cuttings and offsets. With moderate growth and moderate upkeep, it rarely crowds neighboring plants in a hurry. That gives you a better sense of whether simple trimming is enough or whether it is smarter to plan division, replanting, or thinning before the layout closes in.
Frequently Asked Questions About Red Ammannia
Is Red Ammannia a good beginner aquarium plant?
It sits somewhere in the middle. As a intermediate species with moderate maintenance needs, it is a better fit once you already have the basics of light, feeding, and trimming under control.
Where should Red Ammannia be placed in an aquarium?
This plant usually looks best from the midground into the background. At full size it can reach about 45 cm tall by 15 cm wide, so leave room for it to mature. It is best rooted into the substrate.
Does Red Ammannia need strong light or CO2?
For the best results, provide it with high lighting. Additionally, it is noticeably easier to keep attractive and stable with added CO2.
What water conditions suit Red Ammannia?
Aim for freshwater conditions, a steady current, and a range around 22 to 28 °C, pH 6 to 7.5, and 2 to 12 dGH to keep this species inside its comfort zone.
How does Red Ammannia spread or help the aquarium?
It is usually propagated by stem cuttings and offsets. In the display tank, aquarists value this plant for breaking up sight lines and shelter for fry.

Golden Nesaea
Nesaea crassicaulis
Nesaea crassicaulis, now often classified as Ammannia crassicaulis, is a striking African stem plant known for its thick stems and beautiful golden-orange to deep red foliage. It is a demanding species that requires high light intensity, regular nutrient dosing (particularly iron and micronutrients), and carbon dioxide supplementation to prevent stunting and achieve its vibrant colors. When grown well, it forms an excellent focal point in the midground or background of the aquascape.
Large Ammannia
Ammannia gracilis
Ammannia gracilis is a striking, large stem plant native to West Africa. Known for its deeply colored wavy leaves that range from pale green to intense reddish-pink under optimal conditions, it is a demanding species that requires high light, rich nutrients, and CO2 injection to truly thrive and prevent lower leaf drop.
Bonsai Rotala
Rotala indica
Bonsai Rotala, often historically traded under the erroneous name Ammannia sp. 'Bonsai', is a relatively slow-growing, compact stem plant. It grows strictly upright with thick, fleshy stems and small, rounded leaves that can develop a reddish-orange hue under intense lighting. Its compact nature and slow growth rate make it an excellent choice for midground accents or even foreground placement in larger aquariums.
Giant Red Rotala
Rotala macrandra
Rotala macrandra is a stunning, but highly demanding, stem plant known for its large, undulating, brightly colored leaves. To achieve its signature vibrant red coloration and prevent stunting or leaf melting, it requires intense lighting, strictly managed CO2 injection, and a robust nutrient dosing regimen.
Red Milfoil
Myriophyllum tuberculatum
Myriophyllum tuberculatum is a stunning, finely-leaved stem plant known for its intense red to rust-colored foliage. It is one of the more demanding Myriophyllum species, requiring high light, consistent CO2 injection, and comprehensive water column fertilization (especially iron and micronutrients) to maintain its vibrant coloration and prevent lower leaves from melting or dropping. When grown in optimal conditions, its dense, feathery whorls make it a spectacular focal point in the midground or background.
Mosaic Plant
Ludwigia sedioides
A highly unique and beautiful stem plant best known for its striking diamond-shaped leaves that form geometric, mosaic-like rosettes on the water surface. Though rooted in the substrate, it sends long, brittle stems upward to display its vibrant red and green foliage at the top of the tank. It requires intense lighting, a nutrient-rich substrate, and still surface water to thrive indoors, making it a delicate but highly rewarding centerpiece for advanced aquarists.
