Relevant Information:

You may have known this Dorad as Platydoras hancockii or Amblydoras hancockii but it has now been placed back to the Amblydoras genera as this species was misidentified, and is actually Amblydoras nauticus. Brown body which is quite variable. Two black blotches, one below adipose fin and a large one at the caudal peduncle. Black line runs from caudal peduncle along body just below lateral line which stops posterior to the dorsal fin and takes a downward turn. Irregular spots and blotches to the head area. Aquarium Care: No problem in a normal community tank as long as you can give them plenty of hiding places to make them feel more secure.
