Immediately after the moult
Do not touch or move Acanthoscurria geniculata just because the spider looks soft or pale after moulting. The new exoskeleton needs time to harden.
Keep the Giant White Knee enclosure stable and make sure fresh water remains available without disturbing the spider.
When to feed again
Wait until Acanthoscurria geniculata is moving normally and the fangs have darkened before offering food. Small slings harden faster than large adults.
Do not use one fixed number of days for every Giant White Knee. Spider size and the scale of the moult matter more than a universal timetable.
Remove live prey
No live feeder should be left with a newly moulted Acanthoscurria geniculata. A soft tarantula is vulnerable and cannot defend itself normally.
If prey was missed before the moult, remove it from the Giant White Knee enclosure as soon as that can be done without disturbing the spider.
The exuvia
Once Acanthoscurria geniculata has moved away from the moult, the exuvia can be removed if it is easy to reach. Do not dismantle a secure retreat just to retrieve it immediately.
A suitable Giant White Knee exuvia can be dated and kept for growth records or sexing if the relevant structures are intact.
Returning to normal care
Once Acanthoscurria geniculata has hardened and taken a first meal, return gradually to the normal feeding and maintenance routine.
There is no need to reorganise the Giant White Knee enclosure after a successful moult unless the spider has genuinely outgrown the setup or created a safety issue.
