Bioscape Cloud Terrarium Tall Small Cover Only 20 x 20cm
A replacement glass lid for the Cloud Terrarium Tall Small. This 20 x 20 cm glass cover fits the Bioscape Cloud Terrarium Tall Small (20 x 20 x 35 cm, ARI18), for when the original is broken or you're setting up a second tank without buying a whole new enclosure.
Key features
- Matches the Tall Small footprint – cut to the 20 x 20 cm top opening of the Cloud Terrarium Tall Small (ARI18).
- Holds humidity – a glass cover slows evaporation and keeps humidity up for paludarium and moss builds, without sealing the tank airtight.
- Cheaper than a full replacement tank – buy the lid on its own if the tank itself is fine.

Which Cloud Terrarium does this fit?
This 20 x 20 cm cover is sized for the Cloud Terrarium Tall Small (ARI18) only. The Tall Large has a 30 x 30 cm top opening and needs its own larger cover – check your tank's footprint before ordering, since the two aren't interchangeable.
Suitable for, and not suitable for
- Suitable for: the Bioscape Cloud Terrarium Tall Small (20 x 20 x 35 cm, ARI18).
- Not suitable for: the Cloud Terrarium Tall Large, Wide, or any other size in the range – the footprint doesn't match.
Care and maintenance
Wipe condensation off regularly in a humid paludarium setup to stop an algae film building up on the underside.

Common questions
Will this fit my Cloud Terrarium Tall Large?
No. The Tall Large has a 30 x 30 cm top opening; this cover is sized for the 20 x 20 cm Tall Small only.
Does it seal the tank airtight?
No – it sits on top to slow evaporation and hold humidity, not to create an airtight seal.
Can I buy just the lid without a new tank?
Yes – this listing is the glass cover only, for replacing a broken lid or fitting out a second Tall Small tank.
