Arizona Blonde Tarantula Feeding Guide — Aphonopelma chalcodes

Feed Arizona Blonde Tarantulas according to size, appetite and condition rather than a fixed weekly schedule. Aphonopelma chalcodes is a very slow-growing terrestrial species, so small juveniles often eat more regularly than adults.

How often should you feed?

There is no single feeding interval that suits every Aphonopelma chalcodes. A small sling may take modest meals quite regularly, while a large adult can go much longer between feeds.

If an Arizona Blonde Tarantula has eaten recently and the abdomen already looks well filled, wait before offering more. One refused meal is rarely important on its own.

Choosing prey

Offer Aphonopelma chalcodes established feeder insects that the spider can overpower without a long struggle. Crickets, locusts and roaches are all commonly used where they are legal and appropriately sized.

For very small Arizona Blonde Tarantulas, use smaller prey or a suitable pre-killed feeder if that makes feeding safer. Increase prey size gradually as the spider grows.

Slings and juveniles

Young Arizona Blonde Tarantulas generally moult more often than adults, so they usually eat smaller meals more frequently. Keep portions sensible and remove leftovers from the Aphonopelma chalcodes enclosure.

A juvenile Arizona Blonde Tarantula may stop eating before a moult. If the spider is hiding more, closing its retreat or ignoring prey it would normally take, remove the feeder and give it time.

Adults

Adult Aphonopelma chalcodes do not need to be kept permanently full of food. As the spider approaches an adult size of about 13–15 cm, feeding can usually be spaced farther apart than during rapid juvenile growth.

Use the abdomen as a rough guide for Arizona Blonde Tarantulas. If it is already very large, another heavy meal is unnecessary.

Food refusal and premoult

Food refusal in Aphonopelma chalcodes can happen for normal reasons including premoult, recent rehousing, maturity or a period of lower appetite. Check water, temperature and the enclosure before assuming there is a problem.

If premoult looks likely in an Arizona Blonde Tarantula, remove live prey and keep fresh water available. Do not keep offering new feeders every day.

Feeding after a moult

After Aphonopelma chalcodes moults, wait until the new exoskeleton has hardened and the fangs have darkened before feeding again. Small slings recover faster than large adults.

When an Arizona Blonde Tarantula is ready to eat again, offer a modest first meal rather than several feeders at once.

Water, leftovers and safe feeding

Keep fresh water available to Aphonopelma chalcodes even when the spider is feeding well. Remove discarded prey remains before they sit in damp substrate and begin to spoil.

There is no need to hand-feed Arizona Blonde Tarantulas. Place prey into the enclosure from a sensible distance, use tongs for removing leftovers when needed and keep your hands out of the spider's path.
