Rose Hair Tarantula Enclosure Setup

Because they are terrestrial tarantulas, floor space matters more than enclosure height.

Recommended Enclosure Sizes

Juveniles

• 1–3 gallon terrestrial setups

Adults

• 5–10 gallon enclosure

Important enclosure features:

• Cross ventilation

• Dry substrate

Avoid tall enclosures since heavy-bodied tarantulas can be injured in falls.

• Sand/soil mixes

• Arid bioactive substrate blends

Substrate Depth

Humidity

• Low to moderate humidity around 50–60%

Rose Hair Tarantulas do poorly in overly wet conditions.

A fresh water dish is usually sufficient for maintaining proper hydration.

• Superworms

Feeding Schedule

Spiderlings

This species is notorious for occasional long fasting periods, especially adult females.

Healthy specimens may refuse food for weeks or even months without issue.

Rose Hair Tarantula Growth Rate

This species grows relatively slowly.

Approximate timeline:

• Never disturb the tarantula

• Maintain access to fresh water

• Avoid feeding until fangs harden

Freshly molted Rose Hair Tarantulas often display especially vibrant coloration.

Do Rose Hair Tarantulas Bite?

As a New World species:

While generally docile, individual temperament can vary.

Rose Hair Tarantulas can adapt well to semi-arid bioactive setups.

Common additions include:

• Springtails
