Etymology: Dicrossus: Greek, di = two + Greek, krossoi = tassel (Ref. 45335); gladicauda: The specific name is derived from the Latin gladius, meaning sword, and cauda, meaning tail, alluding to the sword-like streamer of the dorsal lobe of the caudal fin in adult males..

Descrição breve
Chaves de identificação | Morfologia | Morfometria
Espinhos dorsais (total) : 14 - 15; Raios dorsais moles (total) : 8; Espinhos anais: 3; Raios anais moles: 6 - 7. Distinguished from all congeners by the conspicuously asymmetrical caudal fin characterized by the long filamentous streamer of its dorsal lobe in adult males. Most similar to Dicrossus filamentosus, but can be differentiated by having a lyreate caudal fin, both the marginal rays of the dorsal and the ventral part of caudal fin are distally produced into a filamentous streamer (Ref. 76847).
Found in a typical blackwater habitat with clear, acidic and very soft tea-colored water, with total and temporary hardness <1° dH (Ref. 76847). Encountered along the bank of small rivulet in zones of extremely shallow water, approximately between 10 and 50 cm depth, where this species occurs either in a layer of dead leaves covering the bottom of the bank side or among the submerged terrestrial vegetation (Ref. 76847).
