Epiplatys multifasciatus Breeding Guide

Breeding the many-banded panchax Epiplatys multifasciatus: a non-annual plant-spawner of the multifasciatus group, regarded as the hardest Epiplatys to propagate.

Overview

Epiplatys multifasciatus is a non-annual African killifish of the Congo River basin, recorded from Cameroon, the Republic of Congo and the Democratic Republic of the Congo plus the upper Ogowe and upper Kouilou-Niari, where FishBase reports it from streams, small rivers and brooks under forest cover. FishBase gives a maximum length of about 6-7 cm and notes the species as difficult to maintain in aquaria.

Sexing

Within Epiplatys, males are generally more colourful, longer-finned and larger than the plainer females; in this stockier group the body bars are pronounced in both sexes.

Conditioning

Tropical Fish Hobbyist advises pre-conditioning females with quality foods for about a week before pairing, which accelerates spawning. When the female is then introduced to the male, spawning generally commences quickly.

Breeding Setup

As a plant-spawner, the species deposits eggs among the roots of floating vegetation or on nylon spawning mops; Tropical Fish Hobbyist notes mops of nylon or 100% acrylic yarn reaching from a float to the bottom are the most popular medium for plant-spawning killifish. Dense plant cover reduces stress on females, which are driven by males whether or not they are carrying eggs.

Spawning Behaviour & Trigger

Eggs are deposited on the medium over several hours to days. Tropical Fish Hobbyist explicitly identifies the multifasciatus group as the only Epiplatys group considered difficult to propagate, so patience and good conditioning are important.

Egg & Fry Care

Eggs of plant-spawning Epiplatys have a protective chorion and can be handled hours after spawning; daily water changes reduce the need for antifungal treatment. Tropical Fish Hobbyist gives transparent, comparatively large eggs that hatch in roughly 11-13 days at about 23 C for related species, with full-term water incubation acceptable. Newly hatched fry take newly hatched brine shrimp from day one in a small grow-out container.

Common Challenges

Low fecundity and the group's reputation for difficult propagation are the chief obstacles, alongside the species' general sensitivity in captivity. Stable soft, warm water (FishBase lists 24-28 C) and a steady supply of live food for fry give the best results.
