My Maroon Clownfish female digs into the sand bed below the pair's spawning territory, but I've never seen my Yellow Tang exhibit this behaviour, so no clue as to why yours is doing this. Since my clownfish are a mated pair & spawning, I always assumed the sand digging was related to a territorial and/or nesting instinct. Are there more Tangs in your tank?
