They don't need a lot of water in general. Much like aloe it should be able to go weeks without watering. Probably going to play it by sight and see when it seems to need a bit of water. Overwatering will make it grow too fast and make weak stems. You can probably already tell that this particular plant has already been watered too much. That middle stem is a giveaway. They're usually low growing and clump.
I'm also going to have to make sure he gets plenty of sun when I can manage it. They're desert plants and are used to sunny conditions. Again it will keep it from getting too leggy.
