Etymology: Nimbochromis: Latin, nimbus = stormy, rainy + Greek, chromis, a fish, perhaps a perch; it has dark clouded melanic blotches on the body (Ref. 45335); polystigma: Derived from the Greek "polus" ("polu-" in compound words) = many and "stigma" = mark, spot, referring to the numerous spots on the body and pectoral fins (Ref. 55922).

Espinhos dorsais (total) : 15 - 17; Raios dorsais moles (total) : 9 - 12; Espinhos anais: 3 - 4; Raios anais moles: 9 - 11. Diagnosis: dark spots on pectoral fins; pattern of speckles on body and head; without conspicuous dark bars radiating from the eye; no downward-directed snout; mouth terminal; premaxillary pedicel length <34% head length (Ref. 55922).
Most common in mixed rock-sand habitats and vegetated areas (Ref. 55922). Occurs in small groups in rocky areas with beds of Vallisneria and Potamogeton (Ref. 3817). Feeds mainly on fish (Ref. 267). Hunts in pairs (Ref. 3817) or in large groups (Ref. 3817, 55922). When singly, sometimes ambushing prey by lying motionless on the substrate, but not on its side (Ref. 55922).
