I just recently thought I lost a Silver tipped shark. Same situation....woke up one morning & he was just gone. We looked everywhere for him to no avail. I just found what was left of him yesterday when I done a tank clean. He had gotten stuck inside of the castle decoration & I couldn't see him until I picked the castle up & turned it over to clean under it. I would check inside any decorations you might have.
