Crenicichla marmorata Breeding Guide

Breeding notes for the marbled pike cichlid Crenicichla marmorata (Lugubria marmorata), a large predatory Amazonian cave spawner.

Overview

Crenicichla marmorata, the marbled pike cichlid, was described by Pellegrin in 1904 and is now placed in the genus Lugubria as Lugubria marmorata. According to Wikipedia and FishBase it occurs in the Amazon River basin, specifically the southern tributaries of the Amazon in Brazil from the Madeira River to the Tocantins River, and reaches about 28 cm (11 in). The IUCN lists it as Least Concern.

Breeding Setup

FishBase records a temperature range of 26-28 degrees C for this freshwater, benthopelagic species. Because it is a large, predatory pike cichlid, a breeding tank must be spacious, warm and well filtered. The Aquairi record classifies it as a cave spawner of advanced breeding difficulty, so caves, crevices and other enclosed spawning sites should be provided.

Common Challenges

Pike cichlids of this size are demanding to breed: forming a compatible pair without serious aggression is the main hurdle, and large predators require generous space and robust filtration. The sources consulted do not document specific spawn sizes, egg-development times or detailed fry-rearing data for this species, so these are omitted rather than estimated.
