Polka Dot Squeaker Breeding Guide

Why Synodontis angelicus is not bred in home aquaria; captive reproduction has occurred only via hormone injection, so trade stock is largely wild-caught or farm-induced.

Overview

The polka dot squeaker (Synodontis angelicus) is an African mochokid catfish from slow-moving river areas of the Democratic Republic of the Congo, Cameroon and the Republic of the Congo. It reaches up to 25 cm standard length in aquaria. It is among the most sought-after Synodontis, but is not a fish that can be bred in a home tank.

Sexing

Mature females display somewhat reduced coloration compared to males. Definitive sexing requires examining the genital papillae with the fish held ventral-side up beneath the pelvic fins: males show a pointed, ridged papilla with a visible spermatoduct, while the female's is more rounded. Most fish reach sexual maturity only after two or more years.

Egg & Fry Care

Because natural aquarium spawning is undocumented, there is no reliable hobby record of egg or fry care. Any captive-bred stock results from injected hormones under controlled commercial conditions rather than tank pairing.

Common Challenges

The natural triggers that induce spawning in this species have not been replicated in aquaria, so hobby breeding is not a realistic goal. Keep the polka dot squeaker as a display fish at 24-28 °C, pH 6.0-8.0 and 3-20 dH, and source captive-bred specimens where possible to reduce pressure on wild populations.
