How to Quarantine a New Terrarium Pet
A new animal can look completely healthy and still carry something worth catching before it reaches the rest of your collection.

Quarantine only matters if you already have other animals, but it's worth planning for even on a first purchase, since most keepers add a second animal eventually. The point isn't distrust of the seller — parasites and low-grade infections often don't show symptoms right away.
Why quarantine even a healthy-looking animal
Internal parasites, respiratory infections and some fungal issues can take weeks to produce visible symptoms. An animal that looks and acts normal on day one can still be incubating something that spreads quickly once it shares air, substrate or a clean-up crew with an established enclosure.
How long to quarantine
30 to 90 days is a common range depending on species, with a fecal exam from a reptile- experienced vet before introduction being the most reliable way to shorten that window with confidence rather than guessing.
Keep the quarantine setup simple
A bare or paper-towel-lined enclosure makes it far easier to spot abnormal stool, shed issues or parasites than a fully bioactive setup would. Save the bioactive build (see our bioactive terrarium guide) for after quarantine clears, in the animal's permanent enclosure.

Feed, clean and handle quarantined animals after your established collection, not before, and wash hands or change gloves in between. Keeping separate tools (water dishes, tongs, hides) for the quarantine enclosure reduces cross-contamination risk further.
Quarantine protocols vary by species and by what else is already in your collection — check with a reptile-experienced vet for guidance specific to your situation.
