Enclosure shape and space
Pinkfoot Goliaths are terrestrial, so the enclosure should provide plenty of floor space, secure footing and a low fall height. Give Theraphosa apophysis a snug hide at ground level and enough substrate for normal digging.
Do not put a small Pinkfoot Goliath straight into an adult-sized enclosure simply because the species eventually reaches about 25–28 cm (10–11 in). Match the setup to the spider's current size so it can find prey, reach water and settle into a retreat without disappearing into a large amount of unused space.
Substrate and retreat
For Theraphosa apophysis, use enough substrate to let a Pinkfoot Goliath dig and to keep the distance between the substrate surface and lid low enough to reduce fall risk. Keep stones, heavy cork and other hard decoration low and secure.
With Theraphosa apophysis, young Pinkfoot Goliaths may dig more, while some become more visible as they grow. If a spider digs, webs over its entrance, or stays hidden for a while, leave it alone. The hide is there to make the spider feel secure.
Moisture and ventilation
For Pinkfoot Goliaths, use moisture-retentive substrate with strong airflow and constant water. You do not need every part of the substrate to be equally wet. Adjust the amount of water to how quickly the enclosure actually dries.
Ventilation is just as important for Theraphosa apophysis as moisture. Persistent condensation, a stale smell or substrate that stays wet for days usually means the enclosure needs less water, more airflow, or both.
Water dish and access
Every Pinkfoot Goliath should have access to fresh water. For Theraphosa apophysis, use a shallow, stable dish and place it somewhere you can reach without dismantling the spider's retreat.
For Theraphosa apophysis, leave enough clear space near the opening to add prey, remove food remains and refill the water safely. If every basic job means pulling apart webbing, moving cork or disturbing a burrow, change the layout.
Temperature and placement
A practical temperature range for Theraphosa apophysis is 22–26°C. Put the enclosure somewhere the room temperature changes gradually, away from direct sunlight, radiators and electronics that create local hot spots.
Do not attach a heat mat directly to the Theraphosa apophysis enclosure. If the room is genuinely too cold, warm the room instead of creating one concentrated hot surface against the container.
Security and maintenance
An individual Pinkfoot Goliath can react differently from another of the same species, so check where the spider is before opening the enclosure. Make sure doors and lids close securely and that ventilation holes are too small for Theraphosa apophysis to escape through.
When maintaining Theraphosa apophysis, use long tools when they make the job safer and keep a catch cup ready for rehousing. Handling is not necessary for routine care, and a well-planned enclosure should let you do most jobs without putting your hands near the spider.
When to rehouse
Rehouse a Pinkfoot Goliath when the enclosure has genuinely become cramped or difficult to maintain. For Theraphosa apophysis, a retreat that no longer fits the spider, too little substrate for normal behaviour or awkward access to water are better reasons to move than the spider simply touching a wall.
Prepare the new enclosure completely before moving Theraphosa apophysis. Add the substrate, retreat and water dish first, check the lid and ventilation, and make sure any cork or decoration is stable before the transfer begins.
What a good setup should achieve
A good enclosure for Theraphosa apophysis lets the spider behave normally and lets the keeper carry out basic care without repeatedly disturbing it. The enclosure shape, substrate and retreat should all suit the same terrestrial lifestyle.
Once a Pinkfoot Goliath has settled in, resist the urge to keep rearranging the enclosure for appearance. With Theraphosa apophysis, if the spider is secure, fresh water is easy to provide and the moisture and ventilation are working well, the setup is doing its job.
