This is the way I keep my tarantulas, theses methods work for me but are not set in stone and there are many differing ways of keeping your spiders. Many people have differing ways and if it works for you and the spider then that is all that matters.
HOUSING : I keep my tarantulas in plastic or glass tanks with ventilated lids or ventilation strips in the glass tanks. The ventilation needs of the particular species can then be met by covering some of the lids ventilation. I keep terestrial spiders in these tanks, they are lighter than glass but the downside is they scratch and mark easily meaning they become difficult to see through eventually. For arboreal spiders I use tall glass tanks, they are heavier than the plastic ones but are better suited to arboreal tarantulas as they give more height than floor space. you can also use sweet jars, sandwich boxes anything really that is big enough. For the spiderlings I use small screw top food containers and various size jars.I drill small holes in the tops, or in the sides so that they can be stacked. They are then kept in a heated wooden vivarium, this works well for keeping numbers of slings.
SUBSTRATE: I use a mixture of Peat, Forest bed or coir ( an expanable natural substrate that is in a brick that you soak in water and it expands) and vermiculite ( Inert mineral substance that as good moisture holding properties). The forest bed/coir type substrates are ok if the species you are keeping do not need high humidity as in damp conditions it can develop mould problems. For arboreals i use just vermiculite for its moisture holding properties.
DECORATIONS: I supply a hide and water dish, the hide can be a piece of cork bark or half a plant pot. In the Arboreal tanks I use a piece of bark leaning against the sides for the spider to climb on and web against. I used to try to decorate the tanks with plastic plants etc but they never stayed where i put them and the prey used to hide in them and make it difficult for the spider to catch them.
HEATING: I use heatmats that are fixed to the wall behind the tanks, the tanks are then placed on racks infront . The mats are on thermostats so that they cant overheat in the summer.
WATER: A water dish is supplied in every tank, the size is dependant on the size of the spider and its humidity needs - Higher humidity - larger dish, Lower humidity - smaller dish. You can use anything that is available really like lids, plastic plant pot saucers etc.
HUMIDITY: The humidity needs for each spider is as said above achieved with differing sized water dishes, covering ventilation and spraying the tank with water or over filling the water dishes every now and then to create a wetter corner of the tank.
FEEDING : I Feed my Tarantulas mostly on Brown or black crickets of appropriate size. I also use Locusts especially for the adult spiders and to a lesser extent mealworms, wax worms . I try to remove all uneaten prey after 24 hrs If i can. I feed 2-3 crickets at a time about once a week.
UPKEEP AND CLEANING : I just spot clean the tanks as and when I can removing uneaten food and leftovers when I see them. And keep the water dishes full at all times if possible.
HANDLING: I dont handle my spiders if I can help it, as I dont think it benefits the spider at all. People do like to handle some of the more docile tarantulas and that is their choice.
TOOLS: Long Tweezers for removing uneaten/ leftover crickets, Thermometers for measuring temperature, various sized containers for moving spiders and paint brushes or chopsticks for moving spiders out of the way.
