Spotted Raphael Catfish Breeding Guide

Why Agamyxis pectinifrons is not bred in home aquaria; the only reported reproduction is hormone-induced, with no documented natural aquarium spawning.

Overview

The spotted raphael catfish (Agamyxis pectinifrons) is an armoured doradid from the Amazon basin of Bolivia, Brazil, Colombia and Peru, reaching 120-150 mm standard length. It is a hardy, nocturnal display catfish but is not a realistic breeding subject for the home aquarium.

Sexing

Mature females tend to be noticeably fuller-bodied than males. This is the primary visual distinction between the sexes; no other reliable external difference is reported.

Egg & Fry Care

Because natural spawning has not been observed in aquaria, there is no reliable account of egg or fry care for this species under home conditions. Any reproduction has relied on artificial hormone induction rather than spontaneous tank breeding.

Common Challenges

The natural cues that trigger spawning in this species have not been replicated in aquaria, so hobby breeding cannot be relied upon. Maintain the spotted raphael as a display fish at 22-26 °C and pH 5.5-7.5 with ample hiding places, and handle it with care because of its sharp pectoral and dorsal spines.
