The right selection is very important for the terrarium success.
Choosing the Right Substrate Mix
A good substrate mix typically consists of several components. Sphagnum moss is an excellent moisture retainer and is a good base. Coco coir or peat moss add to the moisture retention and offer a good environment for the invertebrates. You can include a small amount of leaf litter, such as oak or magnolia leaves, as these provide food and shelter for the cleanup crew. The substrate should be a mix that is well-draining to prevent the build-up of stagnant water. The ratio of each component can vary depending on your specific needs and the tarantula species. Experiment to find a mix that works well in your particular environment. Make sure that all components are organic and free from pesticides.
Importance of Drainage Layer

A drainage layer is crucial to prevent waterlogging and root rot in your plants. Place a layer of gravel, clay pebbles, or other inert material at the bottom of the terrarium, below the substrate mix. This layer provides a space for excess water to collect, preventing it from saturating the substrate and harming the roots of your plants. A drainage layer also helps to maintain air circulation within the substrate, preventing anaerobic conditions that can lead to the growth of harmful bacteria and fungi. Ensuring good drainage is an investment in the overall health of your bioactive terrarium and, consequently, your tarantula.
Essential Tip 2 Plants Selection and Placement
Choosing the right plants is critical for the success of a bioactive terrarium. Select plants that thrive in the humidity and lighting conditions of your tarantula’s enclosure.

Proper plant selection and placement will help to create a more natural and engaging habitat for your tarantula.
Best Plants for a Bioactive Terrarium
Some excellent plant choices for a bioactive tarantula terrarium include pothos, spider plants, ferns, and bromeliads. Pothos are easy to care for and can tolerate low light conditions. Spider plants are also relatively low-maintenance and can help with humidity regulation. Ferns add a touch of elegance and can thrive in humid environments. Bromeliads are particularly appealing due to their unique appearance. When choosing plants, consider the size of the enclosure, the tarantula’s temperament, and the overall aesthetic you are aiming for. It’s important to research the plant’s specific needs to ensure it thrives in the terrarium environment.
Planting the Terrarium

Before planting, thoroughly rinse the plants to remove any potential pests or pesticides. Arrange the plants strategically, taking into account the tarantula’s need for hiding places and open space for movement. Consider the light requirements of each plant and place them accordingly. You can use a variety of techniques to plant, such as directly planting into the substrate or using small pots to contain the roots. Ensure the plants have adequate access to light and water. After planting, lightly water the plants to help them settle in. With proper care and planning, your plants will become a thriving part of your bioactive terrarium.
Essential Tip 3 Invertebrate Clean-Up Crew
The invertebrate cleanup crew is a vital component of a bioactive terrarium. These small creatures work tirelessly to break down waste, recycle nutrients, and keep the terrarium healthy. They feed on decaying organic matter, such as uneaten food, dead leaves, and tarantula waste, preventing the build-up of harmful bacteria and fungi. The selection of the appropriate clean-up crew depends on the size of the terrarium, the tarantula species, and your personal preferences. A well-established cleanup crew greatly reduces the need for manual cleaning.
Types of Clean-Up Crew
Springtails and isopods are the most common and effective members of a cleanup crew. Springtails are tiny, wingless insects that thrive in humid environments and feed on mold and decaying matter. Isopods, often called pillbugs or woodlice, are crustaceans that consume decaying leaves, feces, and other organic material. Other useful additions might include certain types of mites and small beetles. The right combination of these invertebrates will ensure the healthy functioning of your terrarium. Consider the size of the enclosure and the tarantula’s size when selecting the appropriate species for your cleanup crew. Providing leaf litter as a food source will aid them.
Introducing the Clean-Up Crew

When introducing the cleanup crew, start with a reasonable quantity, and add more as needed. Springtails can be easily introduced by sprinkling them onto the substrate. Isopods can be gently placed into the terrarium. Before introducing, make sure the terrarium is properly established. Provide a source of food and shelter for the cleanup crew, such as leaf litter and pieces of decaying wood. Once established, the cleanup crew should be largely self-sustaining, with minimal intervention needed from you. Regularly check their populations and ensure they are thriving. You should notice them within a few days, and they will start to actively keep the enclosure clean.
Essential Tip 4 Maintaining Humidity and Temperature
Maintaining the correct humidity and temperature is crucial for the health and well-being of your tarantula. Tarantulas thrive in specific humidity and temperature ranges, and deviations can lead to health problems such as dehydration, molting issues, or even death.
