Red Root Floaters (Phyllanthus fluitans)

A Vibrant Floating Aquarium Plant with Striking Red Foliage

Description

Red Root Floaters (Phyllanthus fluitans) are one of the most sought-after floating plants in the freshwater aquarium hobby. Native to the slow-moving waters of South America, these beautiful floating plants are known for their round, heart-shaped leaves that develop stunning shades of red under high lighting. Their distinctive bright red roots create an eye-catching display while providing shelter and security for fish, shrimp, and fry.

Red Root Floaters help improve water quality by absorbing excess nutrients, reducing nitrates, and competing with algae for available resources. They are an excellent addition to planted aquariums, shrimp tanks, breeding setups, and natural aquascapes.

Care Level

Easy

Temperament

Peaceful

Size

Individual plants typically grow 0.5–1 inch (1–2.5 cm) across, forming attractive floating mats as they multiply.

Lifespan

Perennial with proper care. Under favorable conditions, Red Root Floaters reproduce rapidly by sending out runners.

Diet

Red Root Floaters absorb nutrients directly from the water column. For optimal growth and coloration, provide:

• Comprehensive liquid fertilizer

• Iron supplementation

• Micronutrients

• Moderate nitrate levels

CO₂ supplementation is not required.

Tank Size

Suitable for 5 gallons or larger.

They thrive in aquariums with calm surface water and minimal surface agitation.

Water Parameters

• Temperature: 68–82°F (20–28°C)

• pH: 6.0–7.5

• GH: 2–12 dGH

Stable water conditions and gentle surface movement will encourage healthy growth and vibrant coloration.

Behavior & Compatibility

Red Root Floaters are compatible with virtually all peaceful freshwater fish, shrimp, and snails. Their extensive root systems provide excellent cover for:

• Shrimp

• Fry

• Bettas

• Gouramis

• Small schooling fish

• Livebearers

They also help diffuse bright aquarium lighting, creating a more natural environment for species that prefer shaded conditions.

Notes

• Develop their deepest red coloration under medium to high lighting.

• Gentle surface flow is essential; excessive agitation can damage the plants.

• Excellent for reducing nitrates and improving water quality.

• Reproduce quickly by sending out runners.

• Long red roots provide shelter for shrimp and baby fish.

• Easy to propagate by separating daughter plants.

• Ideal for planted aquariums, shrimp tanks, breeding tanks, and nature-style aquascapes.

Frequently Asked Questions

Q: Why aren't my Red Root Floaters turning red?
A: Their coloration depends on light intensity and nutrient availability. Medium to high lighting, adequate iron, and stable water conditions will promote vibrant red leaves.

Q: Do Red Root Floaters need CO₂?
A: No. They grow well without CO₂, although nutrient supplementation and proper lighting will improve growth and coloration.

Q: Are they safe for shrimp tanks?
A: Absolutely! Their hanging roots provide excellent grazing surfaces and hiding places for shrimp and shrimplets.

Q: Why are my Red Root Floaters melting or dying?
A: The most common causes are excessive surface agitation, water collecting on the leaves, insufficient lighting, or nutrient deficiencies. Calm water and regular fertilization will help keep them healthy.
