Expert Verdict: Clioran PC Starter Kit, Magnetic Lid Small Terrarium
Clioran PC Starter Kit, Magnetic Lid Small Terrarium
The Clioran PC Starter Kit earns its 8.2 by covering the basics well: the magnetic lid works as advertised, the polycarbonate resists the scratches and yellowing you'd see in acrylic within a few months, and you won't need to buy a separate hygrometer or ventilation add-ons. Just know the 7.8 x 5.9 x 11.8 inch footprint is a hard limit, and the included hygrometer is fine for ballpark humidity checks, not precision readings. For the price of a starter setup, it delivers what it promises.
Buying Guide
How to choose the best tarantula enclosure
Tarantula enclosures aren't one-size-fits-all – a fossorial species needs deep substrate for burrowing, while an arboreal species needs vertical climbing space and can die from a fall onto hard flooring. This guide breaks down the five factors that actually affect your spider's health and your ability to maintain the tank without getting bitten or letting it escape.
-
1
Identify Your Species Type
Terrestrial species like Grammostola rosea need floor space over height. Arboreal species like Poecilotheria need vertical enclosures with branches or cork bark. Fossorial species like Cyriocosmus need at least 4-6 inches of substrate depth for burrowing.
-
2
Match Size to Leg Span
Floor space for terrestrial tarantulas should be roughly 3 times the leg span in length and width, not more – oversized enclosures make sedentary spiders miss food and cause stress from excess open space. Arboreal enclosures should prioritize height at 2-3 times leg span with minimal floor footprint.
-
3
Check Ventilation Placement
Cross-ventilation on opposite sides prevents stagnant air and mold growth in humid setups. Mesh or drilled holes need to be smaller than the tarantula's carapace width, since slings and adults alike can squeeze through gaps you wouldn't expect.
-
4
Confirm the Lid Locks
Tarantulas push against lids at night and can lift unsecured lids weighing several ounces. Look for enclosures with sliding locks, screw-down clips, or magnetic latches rated for the size of your spider, especially for New World species that are strong enough to shift lightweight tops.
-
5
Test Front Access Doors
Front-opening acrylic or glass doors let you feed, mist, and clean without reaching over the tarantula, which matters most for arboreal species that can rupture their abdomen in a fall from your hand. Top-opening only designs work fine for calm terrestrial species but slow down maintenance for defensive or fast-moving ones.
How We Tested
We set up all five enclosures with substrate, hides, and water dishes, then housed juvenile and adult specimens (including a 4-inch Grammostola and a 2-inch Tliltocatl) in each for a minimum of three weeks to check ventilation, escape-proofing, and ease of maintenance. We also ran drop tests on magnetic lids and measured actual interior dimensions against listed specs.
- Ventilation hole count and airflow across substrate
- Magnetic lid strength against a tarantula pushing upward
- Front or top access for feeding without escapes
- Sealed seams and corner gaps checked for gaps
- Visibility and cleaning access for daily upkeep
Frequently Asked Questions
Front-opening enclosures let you access the tank without reaching over a defensive or arboreal spider, which lowers the risk of bites and falls during feeding or cleaning. Top-opening designs work fine for terrestrial or fossorial species that stay low, but they force your hand past the spider's line of sight with skittish or fast species like Old World arboreals. For anything in the Poecilotheria or Pterinopelma genus, front access is the safer default.
Glass holds humidity more consistently and resists scratching, which matters for species that need 70-80% humidity like Avicularia or Theraphosa. Plastic is lighter, cheaper, and shatterproof, making it a reasonable choice for dry-climate species such as Grammostola or Aphonopelma that tolerate 60-65% humidity swings. For humidity-sensitive tarantulas, the $15-30 price gap on glass usually pays off in fewer mold and molting issues.
Too many ventilation holes dry out substrate fast, which is a problem for humidity-dependent species, while too few trap moisture and cause mold or bacterial growth on the substrate surface. Cross-ventilation panels on two opposite sides create airflow without concentrating dry spots the way a dozen small drilled holes can. The right balance depends on species: arboreal humidity-lovers need less airflow than terrestrial fossorial species that prefer drier, well-ventilated burrows.
Buyers often oversize the enclosure for a juvenile or sling, thinking bigger means safer, but a tarantula smaller than 2 inches can struggle to find food in a large tank and may become stressed from open space. The standard guideline is floor space roughly 2-3 times the spider's leg span for terrestrial species, sized up gradually as the spider grows. Arboreal species need height over floor space, so applying the same ratio to a vertical enclosure gets the proportions wrong.
Slings under 1.5 inches do best in small containers around 4-6 ounces with minimal open space, since excess room makes it harder for them to locate food and increases stress. As the tarantula molts and grows, you upgrade every few molts rather than jumping straight to an adult-sized tank, typically moving from a deli cup to a 5-gallon equivalent and then to a 10-15 gallon enclosure by adulthood. Rehousing too early into an oversized tank is a frequent cause of appetite loss in juveniles.
A well-built glass or PVC enclosure lasts 10+ years with normal use, since the tarantula itself doesn't damage the structure the way a burrowing rodent might. The parts that fail first are usually the latches, hinges, or foam gaskets on front-opening doors, which wear out from repeated opening within 2-4 years depending on material quality. Most manufacturers only warranty against shipping damage or manufacturing defects, not wear from daily use, so check the return window before buying rather than expecting a long-term warranty.
