Featherfin Squeaker Breeding Guide

Why Synodontis eupterus is not bred in home aquaria and is instead propagated commercially through hormone-induced spawning on fish farms.

Overview

The featherfin squeaker (Synodontis eupterus) is an African mochokid catfish found across the White Nile, Niger and Volta basins and the Chad Basin, reaching up to 30 cm standard length. It is widely kept but is not a fish that hobbyists can expect to breed at home.

Sexing

Females are noticeably plumper than males. Definitive sexing requires examining the genital papillae with the fish held ventral-side up: males show an extended, pointed and ridged papilla, while the female's is more rounded. Sexual maturity takes upwards of two years.

Egg & Fry Care

Because natural aquarium spawning is undocumented, there is no reliable hobby account of egg or fry care for this species. The commercial fry on the market are the product of hormone-induced farm spawning rather than tank breeding.

Common Challenges

The fundamental obstacle is that natural spawning triggers for this species have not been reproduced in aquaria; success has required injected hormones under farm conditions. Keepers should therefore treat the featherfin squeaker as a display species rather than a breeding project, maintaining it at 22-27 °C, pH 6.0-7.5 and 8-20 dH.
