Apistogramma hongsloi Breeding Guide

How to breed the Hongsloi apisto (Apistogramma hongsloi), an Orinoco-basin dwarf cichlid that spawns in crevices with the female caring for the brood.

Overview

Apistogramma hongsloi is a dwarf cichlid known from the Rio Vichada and middle Rio Meta basins in Colombia and the middle Orinoco system in Venezuela. It belongs to the A. hongsloi complex within the A. macmasteri group, part of the larger A. regani lineage, and carries the DATZ code A110. Seriously Fish describes it as a substrate spawner that deposits eggs in crevices or cavities among the decor, with the female handling post-spawning care.

Sexing

Males are larger, more colourful and develop more extended fins than females. Males reach about 55-60 mm standard length, while females measure 40-45 mm. The compact, plainer body of the female contrasts with the elongated finnage of the male.

Conditioning

As a carnivorous dwarf cichlid, A. hongsloi is conditioned on small live and frozen foods. Consistent feeding and stable water bring females into spawning condition. Wikipedia notes that nearly all Apistogramma spawn in crevices, typically in holes in sunken logs or branches or in leaf-litter aggregations, so providing such structure encourages the female to select a spawning site.

Breeding Setup

Provide caves or crevices among the decor as spawning sites. Seriously Fish lists breeding parameters of 23-29 degrees C, pH 5.5-7.0 and hardness of 18-268 ppm, indicating that this species tolerates a wider hardness range than strict blackwater apistos. In smaller tanks the male may need to be removed after spawning because of female aggression.

Spawning Behaviour & Trigger

The female deposits her eggs inside the chosen cavity and tends them while the male defends the wider territory, following the typical Apistogramma harem pattern in which males are usually polygamous.

Egg & Fry Care

The female handles all care of the eggs and fry. No species-specific egg count is published by the consulted sources; care follows the genus pattern of the female guarding the clutch and leading the free-swimming fry.

Common Challenges

Female aggression toward the male during broodcare is the main concern in smaller aquaria. The species is comparatively hardy across hardness levels, which makes it one of the more accessible apistos to breed. As Wikipedia notes for the genus, water conditions affect offspring sex ratios: warmer water results in more males, and in some species lower pH also yields more males, so stable, moderate parameters help produce balanced broods.
