Orange Chromide (Pseudetroplus maculatus) Breeding Guide

The orange chromide is an accessible biparental substrate spawner whose free-swimming fry graze on their parents' protective body mucus.

Overview

Pseudetroplus maculatus (formerly Etroplus maculatus), the orange chromide, is a small cichlid native to peninsular India and Sri Lanka, from Maharashtra through Kerala to Tamil Nadu. It is euryhaline, occurring in freshwater and in brackish estuaries, coastal lagoons and the lower reaches of rivers. It is a biparental substrate spawner and one of the more accessible brackish cichlids to breed.

Sexing

Sexing is not reliable: reported dimorphism is contradictory across sources — some describe red pigment in the dorsal and anal fins, others report sexes as identical — likely reflecting differences between wild populations. Obtaining a group and allowing a natural pair to form is the practical approach.

Conditioning

The species is a generalist that grazes aufwuchs and filamentous algae and accepts high-quality prepared foods, but prefers small live or frozen items such as chironomid larvae (bloodworm), Tubifex, Artemia and mosquito larvae. Wild fish breed in the dry pre-monsoon (December–April) and monsoon (June–September) seasons; a varied diet conditions adults for spawning.

Breeding Setup

Provide spawning surfaces and open substrate in which the pair can excavate nursery pits, which adults do prior to hatching. Slightly brackish water suits this euryhaline species, and a pair forms a temporary bond when reproductively active.

Spawning Behavior & Trigger

Eggs are attached via short filaments that permit a degree of movement. Incubation is approximately 2 days at 27.0 °C, with the fry free-swimming a further 2–3 days later. Free-swimming fry are large enough to accept Artemia nauplii immediately.

Egg & Fry Care

A notable behaviour is that fry graze on their parents' body mucus when they are 1–3 days free-swimming; this contact feeding is reported as important for survival. Parental care can be highly extended, with a pair continuing to defend fry until they are almost as large as themselves. The species also acts as a cleaner of the larger green chromide, removing parasites, though it will opportunistically consume green chromide eggs and fry — relevant when keeping the two together.
