巴西兵鲶 · C001

Overview

Known as C001, Brochis incolicana comes from upper-Negro blackwater. Body pattern is reported to vary considerably, while the eye bar and dark dorsal-base mark appear more consistent. Accurate identification can still be difficult.

Distribution & habitat

Confirmed records are from the Içana in Amazonas, Brazil. Occurrence across the Colombian border is plausible because the river forms a long border section, but remains inferred. Pristine blackwater tributaries and flooded forest provide tea-colored, very soft water with low conductivity and commonly pH 4–6.

Aquarium setup

Provide at least a 120 by 30 cm footprint with fine sand, branches, and dried leaves. Clean rounded gravel is an alternative. Soft acidic conditions and cover are appropriate; wild fish may do best toward the lower or middle portion of the stated pH range.

Diet & feeding

Offer varied sinking foods with small live or frozen supplements. Feed this omnivore directly instead of relying on tankmate leftovers.

Behaviour & compatibility

Keep at least four to six together to support its peaceful social behavior.

Sexual dimorphism

Mature females tend to be larger, broader, and deeper-bodied.

Breeding

A related-cory method may be tried: use at least two males per female and encourage gravid fish with a 50–70% cooler-water change and increased aeration. Provide fine plants or submerged mops for eggs. If spawning occurs, separate eggs from adults and use aerated breeding-tank water for incubation. A three-to-four-day hatch and small live foods after yolk absorption are reference points from the borrowed method, not established timings for this species. A thin sand layer can be tried for rearing.

Notes

Flank spots may remain separate or form a posterior stripe. Occasional surface gulps supplement respiration. Pectoral spines can puncture skin, and associated secretions may be mildly toxic, so handle carefully.
