Peacock Bass Care Guide

Home › Care Guides › Peacock Bass Care Guide

Introduction

Peacock Bass (Cichla sp.) are the apex cichlid predators of South American river systems. With bold gold, black and green patterning and powerfully built bodies, Cichla are highly sought after by large-fish keepers. The Kelberi Peacock Bass (Cichla kelberi) reaches 40-50 cm, making it suitable for a 6-foot aquarium. The Short Body morph is a selectively bred variant with a compressed body that remains slightly smaller.

Tank Setup

• Size: 6 x 2 ft for Kelberi; larger species require 8 ft+.
• Open swimming space: Peacock Bass spend most time in open water. Decor should be minimal — a few large rocks or driftwood for territory, but leave the majority of the tank open.
• Filtration: Powerful — large, messy fish. Oversized external canister or sump recommended.
• Lid: Essential — Peacock Bass jump when startled.

Water Parameters

Temperature: 26-29 C. pH: 6.0-7.5. Hardness: 3-12 dGH. Ammonia/Nitrite: 0 ppm. Nitrate below 30 ppm. Weekly water changes of 30-40% are essential.

Feeding

Peacock Bass are piscivores. In captivity feed: frozen whitebait and lancefish, frozen prawns, large pellets (Hikari Massivore Delite), and earthworms. To train off live food, withhold feeding for 5-7 days then offer frozen food by tongs imitating movement. Most individuals will eventually accept frozen food enthusiastically.

Aggression and Tankmates

Peacock Bass are highly aggressive toward similarly-sized fish and eat anything smaller. Best kept alone or in very large tanks with large Plecos, Bichirs, or large catfish. Never house with other cichlids of similar size.

Breeding

Pairs bond strongly and are devoted parents. Both fish excavate a flat spawning site and guard eggs and fry aggressively. Raise juveniles together, let pairs form naturally, and condition with heavy feeding. Simulate the wet season with large water changes using slightly cooler water.
