Choose the animal first
A substrate that supports an isopod colony or a planted tropical enclosure may be unsafe or unsuitable for a reptile, snake or invertebrate with different needs. Identify the exact species, life stage and feeding practice first.

Build a moisture gradient
Use appropriate substrate depth and a reliably moist refuge only where the species needs it. Allow a drier area and airflow; waterlogged or stagnant substrate is not evidence of a healthy bioactive system.

Add clean-up organisms carefully
Isopods and springtails may support some systems, but they do not replace quarantine, spot-cleaning, drainage checks or removal of contaminated material. Never add a clean-up crew without checking that it will not be eaten or harmed.

Review the whole enclosure
Check plant safety, mould, odour, waste, humidity at the animal’s level and whether the animal can escape or ingest loose material. Specialist review is needed for individual health, substrate choice and any naturalistic setup.
