Apistogramma elizabethae Breeding Guide

How to breed Apistogramma elizabethae, a Rio Negro blackwater dwarf cichlid that spawns in crevices and requires very soft, acidic water.

Overview

Apistogramma elizabethae was described from the lower Rio Uaupes in northwestern Brazil and also occurs in the adjacent Rio Icana, both tributaries of the upper Rio Negro system. It belongs to the A. elizabethae group within the A. agassizii sublineage of the A. trifasciata lineage and carries the DATZ code A208. Seriously Fish describes it as a substrate spawner that lays its eggs in crevices or cavities among the decor.

Sexing

Males are larger, more colourful and develop more pronounced fin extensions than females. Maximum standard length is about 40-50 mm. The intensified coloration and elongated fins of the male contrast with the plainer, smaller female.

Conditioning

As a carnivorous dwarf cichlid, A. elizabethae is conditioned on small live and frozen foods. Because the fry are sensitive, stable water and good condition in the parents are important before spawning. 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 choose a spawning site.

Breeding Setup

Provide caves or crevices and reproduce the blackwater habitat. Seriously Fish lists breeding parameters of 23-29 degrees C, pH 4.0-6.0 and hardness of 18-54 ppm, noting the species requires acidic conditions with negligible carbonate hardness and very low general hardness. In smaller aquaria the male may need to be removed because the female can become hyper-aggressive.

Spawning Behaviour & Trigger

The female deposits eggs inside the chosen cavity and is mostly responsible for post-spawning care of the eggs and fry. Very soft, acidic water is the key trigger and requirement for viable development.

Egg & Fry Care

According to Seriously Fish the fry are highly sensitive to changes in water chemistry; successful rearing requires multiple small daily meals and regular but never large partial water changes. The female leads and guards the fry.

Common Challenges

Maintaining the very soft, acidic conditions this blackwater species needs is the principal challenge, alongside female aggression toward the male during broodcare and the sensitivity of the fry to water-quality swings. As Wikipedia notes for the genus, water conditions also affect offspring sex ratios, with warmer water and, in some species, lower pH producing more males, so breeders should keep parameters stable to obtain balanced broods.
