Plagiomnium sp. 'Butterfly': A Rare Gem for Your Aquarium

If you're searching for a rare and unique plant to elevate your aquarium's aesthetics, look no further than Plagiomnium sp. 'Butterfly'. This extraordinary moss-like plant is known for its butterfly-shaped leaves, offering a striking visual appeal that's perfect for any aquascape.

What Is Plagiomnium sp. 'Butterfly'?

Plagiomnium sp. 'Butterfly' is a moss-like plant often mistaken for liverworts or ferns due to its delicate, overlapping leaf structure. Native to Southeast Asia, this rare species is sought after for its dense, carpet-like growth, which forms lush, green clusters reminiscent of butterfly wings. Unlike other mosses, it has larger, more defined leaves, giving it an almost sculptural quality.

Key Features

• Appearance: small, oval-shaped leaves arranged in a butterfly-like pattern, forming dense green mats.
• Growth Habit: grows horizontally across surfaces, creating a carpet effect.
• Size: can grow up to 2–4 inches tall and spread widely over time.
• Hardiness: moderate to difficult care, best for intermediate to advanced aquarists.

Optimal Care

Lighting

Thrives in moderate to high light (30–60 PAR), 8–10 hours per day. Avoid shaded areas, as low light causes leggy growth and a loss of density.

Water Parameters

Prefers stable, clean water with low organic waste: 68–78°F (20–25°C), pH 5.5–7.0, soft to moderately hard water (2–10 dGH). Gentle water flow is ideal to avoid dislodging the delicate leaves.

CO2 and Fertilization

Can survive without CO2 but grows much faster with it, especially in high-light setups. Liquid fertilizers with micronutrients like iron help maintain vibrant green color and dense growth.

Planting and Propagation

Attach small clumps to rocks, driftwood, or other hardscape with fishing line or aquarium-safe glue; it will naturally anchor and spread over time. Propagate by dividing healthy sections and reattaching them elsewhere in the tank.

Common Problems and Solutions

Slow growth is common without CO2 — add CO2 and ensure sufficient light and nutrients. Melting or discoloration usually points to poor water quality or inadequate light — keep up with water changes and lighting. Algae growth can occur due to its slow growth rate — keep light moderate, balance nutrients, and consider Amano shrimp.

Tank Mates

Popular in shrimp tanks and nano aquariums. Good companions include tetras, rasboras, and dwarf gouramis; cherry, crystal, and Amano shrimp; nerite and other small, non-plant-eating snails. Avoid large, plant-eating fish like goldfish or cichlids.

Pruning and Maintenance

Regular trimming with small, sharp scissors keeps the plant from becoming too thick and blocking light to lower layers, and encourages healthy new growth.
