Choosing a sling enclosure
Use an enclosure that is secure and easy to inspect for a Hispaniolan Giant Tarantula sling. It should be large enough for a retreat and water access but small enough that prey and the spider are easy to locate.
Match the shape to the Phormictopus cancerides terrestrial lifestyle. Arboreal slings need usable height and anchor points, fossorial slings need digging depth, and terrestrial slings need floor space with a low fall height.
Substrate and moisture
For young Hispaniolan Giant Tarantulas, maintain moderate moisture gradient with good airflow and constant water. Small containers change moisture faster than adult enclosures, so check the substrate rather than watering on autopilot.
Do not keep a Phormictopus cancerides sling permanently waterlogged. Good airflow and a sensible moisture gradient are safer than trying to make the whole container equally damp.
Water
Provide fresh water to Phormictopus cancerides as early as the enclosure allows. A very small, shallow water dish can be used for many slings; where that is impractical, keep suitable moisture available until a dish can be added safely.
Check water frequently because tiny dishes and small containers dry quickly. Do not rely on prey alone to hydrate a Hispaniolan Giant Tarantula sling.
Feeding slings
Feed Hispaniolan Giant Tarantula slings small, manageable prey. A pre-killed or disabled feeder can be useful for very small spiders that are not ready to tackle active prey.
Remove leftovers from Phormictopus cancerides before they spoil, especially in a small moist enclosure. Appetite may drop sharply before a moult.
Moulting
Young Phormictopus cancerides usually moult more often than adults. When a sling stops eating and becomes more secretive, premoult is a common explanation.
Remove live prey, keep water available and leave the Hispaniolan Giant Tarantula alone through the moult. Wait until the new exoskeleton and fangs have hardened before feeding again.
Rehousing a growing sling
Rehouse a Hispaniolan Giant Tarantula sling when the enclosure becomes genuinely cramped or difficult to maintain. Prepare the new setup completely before opening the old one.
Because small Hispaniolan Giant Tarantulas can disappear through tiny gaps, check ventilation holes, lid edges and door clearances carefully before moving Phormictopus cancerides.
Simple records
Record moult dates for Phormictopus cancerides if you want to follow growth. A quick note of feeding and moulting is enough; there is no need to turn sling care into a complicated daily log.
Those dates make it easier to see what is normal for the individual Hispaniolan Giant Tarantula, especially when feeding slows or the interval between moults begins to lengthen.
