We have received juveniles of the “Black Lancer” from Indonesia. The adult fish is pitch black with a white caudal fin and a narrow white horizontal stripe running along the middle of the body. The stripe begins below the dorsal fin and extends into the caudal peduncle.
The 4-6 cm juveniles of this up to 20 cm long animal look quite similar in places, but some have white markings on the body; however, they can turn these on and off depending on their mood. In the case of a Bagrichthys macracanthus juvenile, which appears black to the naked eye, the lighter banding does show up in the strong light of the flash.
