A very large, robust rosette plant popular for its broad, spade-shaped leaves. It is an excellent background plant for large aquariums and is widely recognized as a favorite spawning site for Angelfish. It frequently attempts to grow emersed, eagerly sending broad leaves above the water surface to form a dense canopy.
Radican Sword At a Glance
Radican Sword Care and Setup
Layout Fit
Radican Sword usually works best from the midground into the background and needs enough room to mature at about 60 cm tall and 40 cm wide.
Water Window
Aim for freshwater conditions with gentle water movement, plus 20 to 28 °C, pH 6 to 7.5, and 2 to 15 dGH.
Upkeep Rhythm
Expect fast growth with moderate maintenance. Routine trimming keeps it tidy and stops it from drifting into neighboring space.
Radican Sword Care Guide Summary
The Radican Sword is a rosette or crown plant that usually works best from the midground into the background. Give it room to reach about 60 cm tall and 40 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 moderate light, freshwater conditions, and gentle water movement. It usually grows well without added CO2. Keep this species within a comfortable range of 20 to 28 °C, pH 6 to 7.5, and 2 to 15 dGH.
Radican Sword Planting, Feeding & Maintenance
The Radican Sword 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. Most of its uptake happens through the root zone, so root tabs or an enriched bed matter more than frequent water-column dosing. A nutrient-rich substrate helps it settle faster and usually supports fuller growth. Keep the routine steady: moderate 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.
Radican Sword Compatibility
Use these signals as quick context, not hard rules. They help you judge how well Radican Sword is likely to stay in place, tolerate curious fish, and contribute real cover in a mixed planted tank.
Aquarium Benefits
The Radican Sword 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 tough / leathery leaves usually help it hold up in calm community tanks. Once rooted or attached, it is relatively dependable and easier to keep in place around more active fish. It creates meaningful shelter for fry, shrimp, and cautious fish. Its canopy can shade neighboring plants, so leave space around lower growers that need direct light. Aquarists also lean on it for breaking up sight lines, a useful spawning site, surface cover, and a grazing surface, not just for appearance.
Radican Sword Propagation
This species is usually propagated by plantlets and rhizome division. With fast growth and moderate upkeep, it stays manageable with routine thinning and trimming. 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.
Radican Sword Variants
Trade names and cultivated forms do not always change how a plant behaves in the tank. The notes below call out the differences that actually matter in care and layout planning, while anything not mentioned still follows the base profile.
Marble Queen
A popular variegated cultivar featuring highly attractive green and creamy-white marbling on its leaves. It generally requires higher light intensity to maintain its striking patterns and prevent the leaves from reverting to solid green.
Compared with the base plant, it leans toward moderate growth and high light.
Also known as: Marble Queen Sword, Echinodorus Marble Queen
Mini
A compact cultivar that stays significantly smaller than the wild type, making it well-suited for midground placement or smaller aquariums.
This form is most often used from the foreground into the midground and stays around 25 cm tall and 20 cm wide. Compared with the base plant, it leans toward moderate growth. In the aquarium, expect moderate shade cast. It is often chosen for breaking up sight lines, a useful spawning site, and a grazing surface.
Also known as: Echinodorus cordifolius Mini, Mini Radican Sword

Amazon Sword
Echinodorus amazonicus
A classic and highly popular rosette plant known for its bright green, lanceolate leaves. It serves as an excellent centerpiece or background plant that develops a massive root system and thrives when provided with a nutrient-rich substrate. Because of its large broad leaves, it is famously favored by Angelfish and Discus as a spawning site.
Broadleaf Sword
Echinodorus bleheri
The Broadleaf Sword, widely known as the Amazon Sword, is a quintessential rosette plant in the aquarium hobby. It develops large, bright green leaves and a massive root system. As a notoriously heavy root feeder, it thrives when provided with a nutrient-rich substrate or root tabs. Its broad leaves make an excellent centerpiece and are famously favored as a natural spawning site by Angelfish and Discus.
Melon Sword
Echinodorus osiris
A classic and hardy rosette plant known for its beautiful melon-red to golden-pink new leaves that gradually mature to a rich green. Like most Echinodorus species, it develops an extensive root system and heavily relies on substrate nutrition for optimal growth. Its large, broad leaves make excellent focal points and serve as natural spawning sites for cichlids such as angelfish and discus.
Ashy Pipewort
Eriocaulon cinereum
Eriocaulon cinereum is a striking, hedgehog-like rosette plant that is highly sought after by advanced aquascapers. Originating from marshy areas and rice paddies in Asia and Australia, it demands intense lighting, high CO2 injection, soft acidic water, and a nutrient-rich substrate to thrive. It develops an extraordinarily large root system relative to its size, requiring deep and rich aquasoil. Due to its rigid but delicate crown and strict parameter demands, it is recommended only for experienced hobbyists.
Wendtii Crypt
Cryptocoryne wendtii
Cryptocoryne wendtii is one of the most popular and adaptable rosette plants in the aquarium hobby. Commonly traded in color varieties such as 'Red', 'Green', and 'Brown' (which share identical care and sizing), it forms deep, robust roots and thrives in a wide range of water parameters. While prone to 'crypt melt' when first introduced to new water chemistry, it recovers quickly from its established root system.
Spatterdock
Nuphar japonica
Nuphar japonica is a striking aquatic plant known for its beautiful, translucent, arrow-shaped submerged leaves. Grown from a thick, fleshy rhizome or tuber, it requires a nutrient-rich substrate to thrive. If left unpruned, it may send floating lily pads to the surface, but pruning these surface leaves encourages a lush, bushy, submerged growth form. Its delicate leaves are highly palatable and prone to being eaten by herbivorous fish and large snails.
