Inhabit inshore waters to 20 m deep (Ref. 3236), and restricted to the rocky littoral zone (Ref. 38677). Rest on the bottom with the modified maxillary barbels (Ref. 6868). Nocturnally active meanwhile resting beneath rocks and within interstices in the rock or rubble substrata during the day (Ref. 38677). Oviparous (Ref. 205). First report of bi-parental mouthbrooding among catfishes (Ref. 38677). No value as food (Ref. 4967). Stomach contents examined consist of shrimps, occasionally debris from larval insects, and fish remains which apparently are clupeids (possibly Limnothrissa. Aquarium conditions: pH7.6; hardness of water 12; temperature tolerance 25°C; tank capacity, 60L; food, e.g. live worms, Daphnia; aquarium lighting, as dark as possible as long as fishes are visible; a peaceful, bottom-swimming fish which prefers a set-up with rocks, plants, and driftwood in an aquarium (Ref. 6398).
Life cycle and mating behavior
Madurez | Reproducción | Puesta | Huevos | Fecundidad | Larva
First report of biparental mouthbrooding among catfishes (Ref. 38677). Either or both parents rear their eggs and yolk-sac larvae inside the mouth (Ref. 38677). Young are released from the mouth after the yolk-sac has been absorbed and kept guarded by both parents while feeding beneath rocks (Ref. 38677). After feeding, young return to the parent's mouth (Ref. 38677). No evidence of brooding was found among solitary individuals, additionally, females in this group have low gonadosomatic index (Ig) indicating that a strong bonding of pairs precede egg laying (Ref. 38677).
