A marble queen pothos survives inlow lightbut looks better and grows faster in medium tobright indirect light. When the light is too low, the white swirls on the leaves revert to green on the new growth.
Marble queen pothos like their soil to be kept on the dry side. During the spring and summer, water well and then allow the top 50% of the soil to dry out before watering again. During the fall and winter, let the soil get almost totally dry before watering. If in doubt, wait for the leaves to become soft and droop a little before you water. Black leaves indicate over watering while bright yellow leaves mean the plant has gotten a bit too dry before you watered.
