Apistogramma juruensis Breeding Guide

How to breed Apistogramma juruensis, a Brazilian Jurua-basin dwarf cichlid that attaches eggs to cave ceilings; the female cares for eggs and larvae.

Overview

Apistogramma juruensis is a benthopelagic dwarf cichlid of the upper Jurua River basin within the Amazon system in Brazil. According to FishBase it is a cave spawner: eggs are attached to the ceiling of caves and the female cares for the eggs and larvae. As across the genus, the female provides maternal care while the male defends a territory.

Sexing

As is typical for Apistogramma, the species is sexually dimorphic, with males larger and more strongly coloured than females and breeding females most frequently yellow with blackish markings. FishBase reports that sexual maturity is reached after 3-4 months.

Conditioning

As a small predatory dwarf cichlid, A. juruensis is conditioned on small live and frozen foods. Stable soft, acidic water and consistent feeding bring females into spawning condition, reproducing the soft waters of the upper Jurua River basin in which it occurs according to FishBase.

Breeding Setup

Provide caves with a ceiling on which eggs can be attached, in a soft, acidic tank. FishBase gives a temperature range of 22-29 degrees C for the species. Following the genus, warm, soft and acidic water supports spawning and egg development.

Spawning Behaviour & Trigger

Spawning takes place inside a cave, where the female attaches the eggs to the ceiling. According to FishBase the female then cares for both eggs and larvae, while the male defends the surrounding territory in line with the typical Apistogramma pattern.

Egg & Fry Care

The female tends the eggs on the cave ceiling and guards and leads the larvae after hatching. No species-specific egg count is published by the consulted sources, but care follows the maternal pattern documented for the genus.

Common Challenges

As a soft-water Amazonian species, A. juruensis requires stable, soft and acidic conditions for successful spawning. Because detailed species-specific spawning data is limited, observing the fish and following the genus pattern is advisable. Wikipedia notes that nearly all Apistogramma spawn in crevices, typically in holes in sunken logs or branches or in leaf-litter aggregations, so reproducing such structure encourages spawning; it also notes that warmer water and, in some species, lower pH produce more males, so stable, moderate parameters help yield balanced broods.
