Black Foam & Aquarium Silicone Bundle for Vivarium, Terrarium & Aquarium Backgrounds

Create realistic aquarium, terrarium, vivarium, paludarium, pond, and waterfall backgrounds with one complete bundle. Combining professional-grade black expanding foam with 100% aquarium silicone sealant, this set gives you the essential materials to build durable 3D landscapes, attach natural hardscape elements, and create waterproof habitats with confidence.

The black expanding foam forms a rigid, natural-looking base for rocks, cork bark, driftwood, ledges, caves, and custom background designs. Once the foam has cured, the waterproof silicone sealant securely bonds substrate, glass, foam, stone, decorations, and other compatible materials to achieve a realistic finish that lasts.

Whether you're building a custom reptile enclosure, aquascaping a planted aquarium, creating a paludarium, or designing a decorative pond or waterfall, this bundle provides the core materials needed for professional-quality results.
