I don't really know what to say about this but last night once aquarium lights were off I turned on a regular ceiling light to check something on my smaller tank. My anthia in my large tank went berserk dashing across the sand and then buried her head in the sand and filled her entire mouth down to the gills with sand. Nudged her out and she sat on the sand all night. Was normal all day prior and again today. Somebody has nipped her tail. Did the light spook him or any other thoughts? P.S yes I am behind on the glass cleaning this week
