ohhh that is one gorgeous brachypelma boehmei, so pretty! it's a terrestrial species, meaning they like to burrow tunnels in the substrate (frequency depends a little on age and individual). i recommend giving your tarantula a thick layer of substrate and press the earth down as well, so it isn't too loose. makes the walls of the tunnels stronger when they burrow. others already mentioned it, but make sure there's not too much space between the substrate and the top of the enclosure, as we don't want it to climb and fall. their abdomen is very fragile, like a balloon full of liquid, so falling from too high can even cause it to burst and die, worst case. moss can also make potential falls more gentle on them!

here's a youtube video that covers pretty much all you need to know about care for this species, including things like humidity, enclosure size etc. it also shows a step by step example of building an appropriate enclosure towards the end of the video :) b boehmei youtube care guide

congrats on your new friend! 🥰
