85F is an all around good temp for Theraphosa. Making sure they have PLENTY of water and moist substrate.They are from northern and north easter south america. They are found in tropical rain forests on slopes and hillsides with reasonable drainage and above the high water mark in areas that flood. So having said that you want about 80% humidity pretty much at all times(misting or injecting water into substrate with a serynge) and roughly 75-82F temperatures make sure DO NOT exceed 82F in risks of dessication remember cooler is better than hotter. Depending on the size if 2" or bigger provide a little shallow water dish i'd say get some condoment cups(like the ones coleslaw comes in) cut them down to half size, get some "zoomed" river pebbles (i boil mine in a pot to elimite any bacteria or parasites that may or may not be left on them from a package) and fill the cup with them, pour water so it just barely covers the pebbles. if the leg span is under 2 inches put a patch of forest moss in(sold almost in any self respecting pet store) and mist that area twice a week so that the spidelings can drink the droplets of water. Feed with pin head crickets twice a week, remove any uneaten items next day after feeding.
Repeat until you have a nose bleed and the spiderlings are big enough to relocate
Roming room is more important then hight of the enclosure
T.blondi has a defensive demeanor but will not hesitate to spray hairs in your face and then run away
They don't necessarily require pin-head crickets. Medium crickets or even chopped-up big ones will work too. Pin-heads are sometimes hard to come by anyway, because you may need to order them on-line. You can also try mealworms or waxworms, but roaches work best of all.Feed with pin head crickets twice a week, remove any uneaten items next day after feeding.
T blondi slings comes out at an nch, ans after a molt you will have a 2 incher... full grown crickets.well yea i mean you can use anything starting with pinheads allthe way through mean worms, maggots, flightless fruit flies, roach nymps etc.
Pin heads are the easiest to aquire imo unless you have your own colonies of feeder insects
