Names & Classifications
How we measure invertebrates:

We measure tarantulas and spiders in diagonal legspan. This means the distance from the front right to back left leg (or vise versa) when the animal is stretched out.

Cenitpedes we measure the full length of the animal from the antennae to the back legs

Scorpions we typically measure the body-length of the animal.

Size
Cage Requirements

Choose an enclosure at least twice the tarantula's leg span in width, depth, and height. Ensure proper ventilation to prevent condensation and provide a hide to help your pet feel secure.

Diet & Water

Feed your invertebrates crickets, roaches, or mealworms—we primarily use crickets and recommend feeding weekly. Provide a textured, shallow water dish as a drinking source, ensuring it's just water (no sugar, sponges, or additives).

Temperature & Humidity

Keep invertebrates at room temperature (65°F-75°F) and maintain humidity using soil. The soil should be damp but not saturated, resembling the texture and color of coffee grounds.

Soil & Plants

We use organic coconut fiber for our tarantulas because it resists mold and holds humidity well. For bioactive enclosures, choose nutrient-rich soil, ensuring it is free from insecticides and pests.
