One of Shane Zaghini's hybrids ('Gee Whiz' x smithii)
Don't over water - just enough to prevent the plant from drying out & to keep fresh water in the centre.
Light shade or filtered sun / 50% shadecloth - 70% in Summer. Early am or late pm sun.
Very little or the plant will lose colour. Use a pinch of slow release fertiliser higher in potassium than nitrogen..
