River Buttercup

Ranunculus inundatus

Stolon / Runner Plant
Foreground
Carpeting
Midground

An eye-catching, creeping plant native to Australia, recognized by its deeply lobed, umbrella-like palmate leaves. Under high light and CO2, it forms a dense, unique carpet or midground bush, while lower light causes it to grow taller and leggier.

Layout Fit

River Buttercup usually works best from the foreground into the midground and needs enough room to mature at about 15 cm tall and 20 cm wide.

Water Window

Aim for freshwater conditions with a steady current, plus 20 to 28 °C, pH 6 to 7.5, and 2 to 12 dGH.

Upkeep Rhythm

Expect moderate growth with moderate maintenance. Routine trimming keeps it tidy and stops it from drifting into neighboring space.

River Buttercup Care Guide Summary

The River Buttercup is a runner-forming plant that usually works best from the foreground into the midground. Give it room to reach about 15 cm tall and 20 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 20 to 28 °C, pH 6 to 7.5, and 2 to 12 dGH.

River Buttercup Planting, Feeding & Maintenance

The River Buttercup 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 moderate 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.

Aquarium Benefits

Good refuge for shrimp
Good grazing surface
Good refuge for fry

The River Buttercup 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 can be sampled by omnivores, so it fits best with tankmates that do not constantly pick at foliage. 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 does not block much light, making it easier to mix with smaller plants nearby. Aquarists also lean on it for shelter for shrimp, a grazing surface, and shelter for fry, not just for appearance.

River Buttercup Propagation

This species is usually propagated by runners. With moderate 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.

Frequently Asked Questions About River Buttercup

Is River Buttercup 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 River Buttercup be placed in an aquarium?

This plant usually looks best from the foreground into the midground. At full size it can reach about 15 cm tall by 20 cm wide, so leave room for it to mature. It is best rooted into the substrate.

Does River Buttercup 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 River Buttercup?

Aim for freshwater conditions, a steady current, and a range around 20 to 28 °C, pH 6 to 7.5, and 2 to 12 dGH to keep this species inside its comfort zone.

How does River Buttercup spread or help the aquarium?

It is usually propagated by runners. In the display tank, aquarists value this plant for shelter for shrimp, a grazing surface, and shelter for fry.

Asian Watermoss

Salvinia cucullata

Floating Plant
Floating
BeginnerModerate

Salvinia cucullata is a distinct floating fern native to Asia, instantly recognizable by its tightly cupped or hood-like leaves. It thrives in still waters, absorbing excess nutrients directly from the water column, making it an excellent plant for managing water quality and outcompeting algae. The trailing root-like structures (which are actually modified leaves) provide a perfect refuge for fry and shrimp. It requires moderate to high lighting to maintain its characteristic cupped leaf shape; under low light or poor nutrition, the leaves may grow flat.

Congo Anubias

Anubias heterophylla

Rhizome / Epiphyte Plant
Midground
Background
BeginnerLow

A robust, large-leaved rhizome plant native to Africa. It features upright, leathery, lanceolate to elliptical green leaves that make it an excellent background or midground structural plant. Like other Anubias, it is very hardy, undemanding, and should be attached to hardscape or planted with the rhizome completely exposed above the substrate.

Süßwassertang

BeginnerLow

Süßwassertang is a unique aquatic plant that is actually the gametophyte (prothallium) stage of the fern Lomariopsis lineata. Treated functionally as a moss or liverwort in the aquarium hobby, it forms dense, beautiful mounds of translucent, ribbon-like thalli. It is extremely undemanding, adaptable, and thrives in low-tech setups. Because it does not root, it is typically tied or glued to hardscape, or allowed to sink and settle in low-flow areas. It is highly valued by breeders for providing an exceptional grazing surface and dense refuge for shrimp and fry.

A slow-growing, highly sought-after epiphytic aroid native to the fast-flowing streams of Borneo. Known for its resilient, often iridescent leaves and strong clinging roots, it thrives when attached to rocks or driftwood and requires very little maintenance.

Glosso

AdvancedHigh

Glossostigma elatinoides, commonly known as Glosso, is a classic and highly popular aquarium carpeting plant native to the swamps and bogs of Australia and New Zealand. Prized for its ability to form a dense, bright green mat along the aquarium floor, it is often a centerpiece in high-tech nature aquariums. It is a demanding plant that requires intense lighting and carbon dioxide supplementation to creep horizontally; without these, it tends to grow leggy and vertical. Frequent trimming is necessary to prevent the carpet from overgrowing itself, which can lead to the lower layers dying off and the mat detaching from the substrate.

A magnificent, large bulb plant native to Madagascar, recognized by its distinctive, deeply puckered (bullate), dark green, slightly transparent leaves. It is a large background plant that uniquely appreciates strong water flow and requires a nutrient-rich substrate to support its massive root system and rapid growth phases.
