Description

Bioactive Terrarium & Vivarium Background Clay

A mouldable clay-based background material for creating natural-looking planting surfaces, pockets, ledges and textured areas in planted vivariums and terrariums.

Why use a clay-based background?

• Can be applied only where required rather than filling the whole background with expanding foam.
• Can be hand-shaped into pockets, ledges and irregular naturalistic contours.
• Provides a moisture-holding mineral surface for suitable mosses and plants.
• Avoids the carving stage associated with many expanding-foam builds.

Animal-safety wording corrected

Earlier wording described the material as “dart frog safe” simply because it has no volatile curing stage. Absence of solvent fumes is not, by itself, evidence that a material is harmless to amphibians. Amphibian skin is highly permeable, so composition, dissolved residues, loose particles and water runoff all matter.

Frogfather uses this clay-based material in our own planted builds. That is practical husbandry experience rather than a formal toxicological safety test.

Before adding animals

• Build and plant the background before introducing amphibians.
• Allow the finished background to become physically stable.
• Remove loose material and inspect runoff or standing water for suspended residue.
• Confirm that the structure remains attached under the enclosure’s normal misting regime.
• Do not mix additional fertilisers, pesticides, fungicides or other chemicals into the material for an amphibian enclosure.

Plants and nutrients

The blend contains mineral/plant-support ingredients intended to assist planted establishment. We have removed the claim that this automatically makes plants establish “more successfully than inert foam”; plant success depends on species, lighting, moisture, rooting behaviour and overall husbandry.

Does it cure?

This is not a solvent-curing silicone or expanding foam. It sets through its physical clay-based structure rather than a volatile chemical cure. Even so, give a completed animal enclosure a settling and inspection period before livestock are introduced.
