Goliath Tarantula Care Sheet

The Goliath bird eating tarantula is one of the largest spider species in world. It grows to around 12 inches across and is around the size of a dinner plate. Because of its large size, the spider can be attractive to exotic pet owners. It is, however, among the more difficult species to keep.

  1. Housing

    • The Goliath tarantula needs a decent-sized tank to support its large size, preferably a 30-gallon terrarium. Some form of shelter should be placed in the tank, such as a large plant pot or hollow fake log in which the spider can hide. Spread a layer of natural material on the floor of the habitat a few inches thick. Peat moss or cypress mulch both make suitable substrates for the habitat.

    Conditions

    • The spider is native to the humid tropical rain forests of South America, so it does need a certain level of humidity. In captivity it can be kept in slightly drier conditions but should always have a small dish of fresh water in the tank. Occasional, but not excessive misting with fresh water spray is advised. The best temperatures at which to keep the spider are between 78 to 82 degrees Fahrenheit

    Feeding

    • The spider does not have to feed everyday; generally two to three times a week is sufficient. The Goliath in captivity can be fed live crickets, grasshoppers and certain larvae. Occasionally, a live mouse can be fed to the spider, but only once or twice a month. If food is not eaten within 24hrs it should be removed, especially mice. The spider may lose its appetite around the time it molts its skin.

    Handling

    • Some tarantulas can be handled, but the Goliath is not one of them. It is an aggressive spider that will launch irritating hairs from its abdomen and readily bite. Its venom is not deadly, but its bite hurts because of the large fangs. If the spider has to be taken out of the tank it should be coaxed into a smaller holding box using a soft bristled paint brush to limit contact. If the spider is on its back it probably is not dead, it may just be molting, so it should be left alone. A slight increase in misting may help the molting process.
