Barlow’s Apistogramma

A robust Apistogramma with an unusually large head, broad mouth, heavy jaws, and thick lips in adult males. Males develop extended anterior dorsal membranes and a lyre-like caudal fin divided into contrasting colour zones. Females are smaller with a more truncate tail and distinct brood markings.

The combination of enlarged male head and jaws, thick lips, divided caudal colour, extended first dorsal membranes, female breast band, and absence of a caudal-peduncle spot separates it from similar species. Do not confuse it with Apistogramma megastoma.

Males are much larger, with heavier jaws, thicker lips, longer fins, and a divided lyre-shaped caudal pattern. Females are smaller, have a shorter truncate caudal fin, and show strong dark breast and flank markings during brood care.

Use a 75 cm or longer mature aquarium for a pair, with fine sand, leaf litter, wood, several caves, and strong sight breaks. Provide gentle to moderate directional flow without turning the entire tank into high current. A species-focused setup is preferred.

A territorial, pair-oriented dwarf cichlid with unusual brood-care behaviour. Adults may alternate between shelter guarding and carrying larvae or fry.

Best maintained as one compatible pair. Mismatched adults can be aggressive, and a spare aquarium or divider should be available.

Both parents may participate in territory and brood defence. Aggression can shift rapidly during courtship, cave spawning, and mouthbrooding phases.

A species-only aquarium is safest. In a larger display, use only calm upper-water fish that tolerate similar water. Avoid other dwarf cichlids, intrusive bottom dwellers, aggressive fish, and ornamental shrimp.

The type area includes clear acidic forest streams. Soft water near pH 5 to 6 is a sensible target, while moderate flow and high oxygen should be provided without excessive turbulence.

A small-invertebrate predator that should receive varied live, frozen, and high-quality prepared foods.

Feed small portions once or twice daily. Newly imported fish may need live or frozen foods before accepting pellets. Avoid a long-term single-food diet.

A shelter-spawning species with facultative mouthbrooding. Eggs are laid in a cave or shelter. After hatching, the female, male, or both parents may carry larvae or fry in the mouth while also defending the territory. Behaviour varies among pairs and conditions.
