Welcome to Arachnoiden

Keeping tarantulas is a growing pastime. Diversity of tarantula color, size and behavior trigger interest and raise questions. Step onto the webbed mat for your first pet. You’ll find enjoyment & answers, and more questions. The hunt is on.

Arachnoiden has tarantulas for sale from around the world. New hobbyists as well as breeders shop here, also a few resellers. We ship FedEx Priority Overnight from Massachusetts.

We aim to find the tarantulas that you want to keep. As availability and breeding allow, we add new species to the Store. For newcomers we try to always stock good-tempered species like the curly hair tarantula (Tliltocatl albopilosus) and Arizona blond (Aphonopelma chalcodes). Advanced beginners may look for species in other New World genera such as Acanthoscurria, Brachypelma, Grammostola and Psalmopoeus. We nearly always have these tarantulas for sale.

As interest and experience grow, keepers may tend to the larger species in Pamphobeteus, Theraphosa and Xenesthis, or perhaps smaller “dwarf” species in Cyriocosmus, Hapalopus and Neoholothele. Somewhere along the front of advancing experience the hobbyist may undertake Old World species, notable for no urticating (itchy) hairs, but also defensiveness and venom potency. We carry Old World tarantulas for intermediate and advanced keepers who tend to specialize in this area. Increased experience allows exposure to the sheer diversity of all corners of the globe.


The Store format is list-based, with items alphabetized on on a single, scrollable column. The spiderling section is broadest and first on the list. Females for sale are second on the list, males and pairs next. For a photo, tap (mobile users) or hover (desktop users) over a name. You can tap/hover down the list to see each species’ photo. Tap/hover elsewhere to close.

The Learning Curve

Using scientific names (genus species) may be awkward or intimidating at first. We recommend getting used to them. The common name system is fraught with duplications and inaccurate references. You’ll find experienced keepers using scientific names exclusively. Talking with them (and us) will help you learn the names. With repetition you’ll use them without thinking. Remember, the first letter of the genus is always capitalized and that of the species is never capitalized.

Online sources for information are abundant, but beware. Still an authoritative source is The Tarantula Keeper’s Guide by Stanley A. Schultz. A Kindle version is available. The basics and some advanced topics are covered, as well as seeds for further learning. We recommend having this book at hand and may refer to it to answer questions you send our way.

Smart Shopping

Spiderlings (slings) are the most economic form of purchase. Like any young animal they require more attention. Many hobbyists derive extra satisfaction from raising a tarantula from an early stage, but others prefer starting with grown-out specimens; usually that means sexed. Female tarantulas live 3-5x longer than male tarantulas so non-breeders prefer females. Females cost more due to the time needed to raise a sling to a sexable size and because of low demand for males.

As your slings grow and you become sure of it’s sex, you’ll find about half of them are male. What to do with unwanted males? There are various forums on which you can post them for sale (Arachnoboards and Tarantula Forum). We offer our customers the option to trade/sell them back to us. In some cases we can trade your male for a juvenile female specimen of the same or similarly valued species. If we have no current breeding use for him we can post him on Arachnoiden provided you send him with a useable photo and the last molt date. The trade value for us would be about 1/2 his posting price.

As part of a trial program, in cases where we have no current breeding use, we can post your male’s photo and last molt date and you can ship from your location. We can provide a discounted shipping label as needed. When the customer is satisfied with healthy arrival, you’ll be reimbursed your sale price. At some later date, if workload increases substantially, we may charge 5-10% of purchase price, but not for now. We’ll create a special category for this service and it will run on a trial basis, pending customer satisfaction and review [contact us].

Thank you all.
