Singapore Blue Tarantula Feeding Guide — Omothymus violaceopes

Feed Singapore Blue Tarantulas according to size, appetite and condition rather than a fixed weekly schedule. Omothymus violaceopes is a fast-growing arboreal species, so small juveniles often eat more regularly than adults.

How often should you feed?

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

If a Singapore Blue 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 Omothymus violaceopes 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 Singapore Blue 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 Singapore Blue Tarantulas generally moult more often than adults, so they usually eat smaller meals more frequently. Keep portions sensible and remove leftovers from the Omothymus violaceopes enclosure.

A juvenile Singapore Blue 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 Omothymus violaceopes do not need to be kept permanently full of food. As the spider approaches an adult size of about up to about 25–28 cm (10–11 in), feeding can usually be spaced farther apart than during rapid juvenile growth.

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

Food refusal and premoult

Food refusal in Omothymus violaceopes 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 a Singapore Blue Tarantula, remove live prey and keep fresh water available. Do not keep offering new feeders every day.

Feeding after a moult

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

When a Singapore Blue 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 Omothymus violaceopes 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 Singapore Blue 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.
