Etymology: Dicrossus: Greek, di = two + Greek, krossoi = tassel (Ref. 45335); warzeli: Named for Frank Martin Warzel, a skilled German aquarist who collected the type specimens and who first imported the species from the Rio Tapajos to Germany, as well as observed its behaviour, including reproduction in the filed and in the aquarium.
Eponymy: Frank Martin Warzel (1960–2004) was a skilled German aquarist who, according to the authors: “…dedicated most of his life” to research on neotropical cichlids. [...] (Ref. 128868), visit book page.

ການຖ່າຍທອດທາງກຳມະພັນຈາກພໍ່ແມ່ຫາລູກ: 3; ຄີກົ້ນຂອງປາ: 6 - 7. Can be distinguished easily by its three longitudinal rows of dark grey to blackish, horizontally elongate, dash-like spots on the sides of the body; and caudal fin spatulate in adult males. Exhibits clear sexual size and color dimorphism (Ref. 85095).
Body shape (shape guide): elongated.
Inhabits exclusively clear-water rivers. Juveniles measuring about 2.0 cm SL occur in small brooks with sandy bottoms and patches of leaf litter. Observed searching the bottom substrate for small invertebrates and detritus by picking up and turning the leaves. Collected only in very soft water (no detectable hardness) with high acidity, pH value mostly less than 4 (Ref. 85095).
