He’s used to deserts so his water needs are very modest. Let him dry out fully between drinks.
He likes his rays. Give him the brightest spot available. He’ll take all the sun you can give him.
Give a cactus-specific feed, diluted to half strength, about once every two months in spring and summer.
He can get dusty, which isn’t good for him, so clean him when needed. Use a soft brush so you don’t have to get near those spikes.

About cactus euphorbia
The cactus euphorbia looks like the quintessential cactus, although it’s technically not one (it grows very very tiny leaves, which cacti do not). It’s native to Southern Africa, where it stands out in the dry scrublands, basking in the blazing sun. As it grows, sometimes almost ten metres tall, its trunk becomes woody. Eventually, it becomes a strange, bulbous tree. Often it will flower and grow round, red fruit.
As a houseplant it won’t become a tree, or grow flowers and fruit (we don’t have the necessary conditions). It will remain a tall, handsome plant that deals very well with living inside. When caring for it, think desert: Lots and lots of light; not a lot of water.

The milky latex inside it is poisonous, but some indigenous groups in Africa have learned how to turn it into a medicine for a variety of ailments.
