What size tank do I need for a tarantula or jumping spider?

The ideal tank size depends on the species. Tarantulas need more floor space (horizontal room), while jumping spiders thrive in enclosures with more vertical space for climbing. A 2.5 to 5-gallon tank is usually suitable.

Can I use a regular fish tank for my pet spider, or do I need a spider-specific enclosure?

You can use a modified fish tank as a spider enclosure, but it must have proper ventilation, a secure lid, and be escape-proof. Purpose-built spider enclosures are often safer and more convenient.

What’s the difference between arboreal and terrestrial spider enclosures?

Arboreal spider enclosures are tall and designed for climbing species like jumping spiders. Terrestrial enclosures are wider and more shallow, ideal for ground-dwelling spiders like tarantulas.

Do spider starter kits come with everything I need?

Most spider starter kits include a tank, substrate, decor, and feeding tools. However, always check the list of included items, as some kits may require you to buy heating or humidity tools separately.

What’s the best substrate for a tarantula or jumping spider?

Top choices for spider substrates include coconut fiber (Eco Earth), peat moss, and organic topsoil. These substrates help maintain humidity and allow for burrowing behavior, especially in tarantulas.

How do I maintain proper humidity and temperature in a spider tank?

Use a hygrometer and thermometer to monitor conditions. Mist the tank as needed for humidity, and use a heat mat or ambient room heating for tropical species. Avoid overheating.

Is ventilation important in spider enclosures?

Yes. Proper ventilation prevents mold and keeps the air fresh. Cross-ventilation is especially important for jumping spiders, which are prone to mold-related health issues.

What tank accessories do pet spiders need?

Essential spider tank accessories include a hide or shelter, climbing branches (for arboreals), a water dish (for tarantulas), and anchor points for webbing. Minimalism is key—avoid overcrowding.

Can I keep more than one spider in the same tank?

No. Most pet spiders, including tarantulas and jumping spiders, are solitary. Keeping multiple spiders together often leads to aggression or cannibalism.

How often should I clean a spider tank?

Spot clean weekly by removing uneaten prey and waste. Perform a deep clean every few months or when mold or pests appear. Avoid disrupting established webbing when possible.

Are glass or acrylic tanks better for spiders?

Both work, but each has pros and cons. Glass tanks are scratch-resistant and clear but heavier. Acrylic tanks are lighter, offer better insulation, and can be customized more easily.

Can I build a DIY spider enclosure?

Yes. Many keepers make their own DIY spider enclosures using plastic containers, acrylic sheets, and mesh. Just make sure it’s well-ventilated, secure, and escape-proof.

What lighting do spiders need in their tank?

Spiders don’t require special lighting. Avoid direct sunlight and bright artificial lights. Most spiders do best with indirect natural light or standard room lighting.

Where is the best place to keep a spider tank in my home?

Place the tank in a quiet, temperature-stable room, away from direct sun, drafts, and vibrations. Avoid kitchens or windowsills where temperature fluctuates.

What should I avoid putting in a spider tank?

Avoid treated wood, sharp decorations, bright LED lighting, and anything with strong odors or chemicals. These can harm your spider or disrupt its natural behaviors
