Longfin batfish — locally called spadefish — hover in stationary schools of 20 to 40 individuals around the American Tanker's uppermost hull, their large silver disc bodies creating a shimmering mobile canopy over the wreck in the mid-water column. These fish are highly site-faithful and the same school has reportedly been associated with the wreck for multiple diving generations, approaching divers with remarkable boldness.
