Do Banded Trochus Snails require light?

[alfieh0]

I want to add some these to my newly cycled tank, but I currently don’t have a main light. Can these survive in the dark without a light? There will be indirect window light during the day.

No they dont require light. They do however require food (typically algae) which does require light. If your tank is devoid of algae they will need to be fed or they will starve.
