I recently switch my substrate from gravel to sand and my red zebra keeps scooping up sand and dropping it on a specific rock on the opposite side of the tank where is cave is. Is he just getting used to the sand? Or is he playing? I'm not nervous about anything I'm just curious lol. He is also the dominant fish in the tank
