Could be static electricity from walking across the room. Is your LED fixture grounded? I know I have to separately ground each of my individual T5HO retrofit reflectors to keep from getting a tingle when I touch them & the water at the same time. Not unusual for the water and a hanging fixture to be at slightly different voltage potentials in reference to ground. Fluorescent ballasts tend to induce voltage into surrounding objects, but with your LED fixture that shouldn't be an issue.
In any case, it may warrant further investigation. Are you on a GFCI with your equipment?
