Overview

Butterfly Peacock Bass (Cichla ocellaris) is a middle swimmer for aquariums where the layout leaves enough open swimming space and the water stays stable.

Use these values as planning checks, then make sure the aquarium still has room for behavior, group needs, and calm community fish.

Care requirements

With a Intermediate – Advanced care level, Butterfly Peacock Bass is best for aquarists who can keep water quality steady and plan compatibility before adding the fish.

Because it uses the middle part of the aquarium, leave enough open swimming space instead of crowding that part of the aquarium.

With a lifespan of up to 15 years, this is a fish to plan for long term rather than an impulse addition.

Aquarium size and space needs

An aquarium of 900 L or larger can be a reasonable starting point, but it should not be read as permission to overstock.

At up to 75 cm, Butterfly Peacock Bass stays small, but it still needs room to move, feed, and avoid constant competition.

Uses the middle part of the aquarium, so leave enough open swimming space for movement and feeding.

Water parameters

The temperature range for this fish is 24 to 29 °C, which fits many tropical freshwater aquariums. Choose other fish with overlapping temperature needs.

The pH range for this fish is 6 to 7.5. That points to slightly acidic to neutral water, but stability is more important than sudden corrections.

The GH range for this fish is 5 to 15 dGH. That gives some flexibility, but sudden changes are usually more stressful than a stable value that is slightly imperfect.

Temperament and compatibility

Butterfly Peacock Bass should be planned cautiously with compatible fish only, because aggressive temperament data raises the risk of conflict.

Because this fish uses the middle part of the aquarium, compatibility is easier when other fish are not all competing for the same swimming space.
