About This Plant

Eleocharis montevidensis Clumps of grass-like foliage with occasional button-like nuts at the tip.

Quick-Reference Details

Common name: Spike rush
Scientific name: Eleocharis Montevidensis 1
Family: Cyperaceae
Native to: North America
Difficulty: Intermediate
Requirements: Hardy marginal
Available as: 2” and 4” pots

Difficulty — Intermediate

Forgiving enough for hobbyists with one tank of experience. Watch lighting and nutrient levels for best growth.

CO2 & Fertilization

CO2 is optional. Growth improves with supplementation, but the plant survives and stays presentable without it.

Tank Size & Setup

Works in tanks 10 gallons and up. Match the plant size to your tank depth for the cleanest aquascape.

Aquascaping & Placement

Position to suit your aquascape — most placements work as long as light reaches the leaves.

Tank-Mate Compatibility

Compatible with the full range of community-tank species — tetras, rasboras, livebearers, corydoras, and most other peaceful freshwater fish do not damage the foliage. Tough enough for cichlid tanks and goldfish setups where most other plants are uprooted or eaten — the leaves are too leathery for those fish to chew through.

Common Care Issues

Slow initial growth

Most aquarium plants pause for 2-4 weeks after planting while they convert from their nursery-grown emersed form to fully submerged growth. New leaves that emerge underwater will look thinner and slightly different — this is the plant adapting, not a problem.
