Spike Moss (Selaginella sp.)

Peacock Spikemoss is a striking low-growing moss relative that thrives in high-humidity terrariums, making it a natural choice for bioactive and planted vivarium builds. This large specimen from ProRep's curated live plant range is selected specifically for terrarium suitability — not just a generic houseplant, but a species chosen for how it performs in a living setup.

Why Live Plants in a Terrarium

Living plants do more than look good. They provide natural cover, maintain ambient humidity, create shade gradients, and contribute to the overall wellbeing of the animals living alongside them. As bioactive and naturalistic keeping becomes standard practice, choosing the right species matters as much as choosing the right substrate or lighting.

Selaginella sp. — What You Need to Know

Peacock Spikemoss belongs to the Selaginella genus and has specific requirements that must be met for it to establish and thrive. It needs constantly moist soil and consistently high humidity — this is not a plant for arid or semi-arid vivarium setups. Given the right conditions, it spreads rapidly, forming a dense, lush green carpet across the vivarium floor.

Lighting and Airflow

Spikemoss will tolerate bright light or light shade but must not be placed in the direct path of hot spot lamps, which will cause it to dry out and die back quickly. Adequate airflow is equally important — stagnant, still air leads to rot. Good ventilation within the enclosure is essential for this plant to remain healthy long-term.

Suitable Vivarium Setups

• High-humidity tropical and jungle terrariums only
• Pairs well with bioactive builds using live substrate and microfauna
• Best suited to small or lightweight animal species — delicate foliage is easily damaged by heavier inhabitants
• Not suitable for arid, desert, or low-humidity enclosures

When conditions are right, Peacock Spikemoss establishes quickly and rewards the keeper with dense, vivid ground coverage that genuinely enhances the natural feel of a planted vivarium. ProRep's live plant range is one of the most considered selections available in the UK hobby, and this large specimen gives you a strong head start.
