PEACOCK BASS TEMENSIS (Cichla temensis)

Peacock Bass Temensis Overview

The Temensis Peacock Bass is one of the most impressive and highly sought-after species of peacock bass in the aquarium hobby. Scientifically known as Cichla temensis, it is famous for its powerful body, predatory behavior, striking coloration, and potential to reach a substantial adult size.

Unlike smaller peacock bass species, Cichla temensis is particularly appealing to monster-fish keepers because of its combination of size, athletic behavior, bold personality, and spectacular adult coloration.

At Monster Aquarium Canada, Peacock Bass Temensis is an excellent choice for experienced aquarists looking to keep a true large predatory freshwater fish.

Appearance and Coloration

Powerful Body Shape

Cichla temensis has the classic streamlined, muscular body associated with peacock bass. It is built for explosive acceleration and ambush predation.

The large mouth and powerful jaws are perfectly adapted for capturing smaller fish.

Adult Coloration

One of the most exciting characteristics of Cichla temensis is its dramatic coloration.

Depending on age, sex, mood, breeding condition, and whether the fish is displaying its juvenile or adult color phase, coloration can include:

• Green
• Blue-green
• Yellow
• Gold
• Dark vertical markings
• Black
• Iridescent blue
• Orange and reddish highlights

Mature specimens can develop an extraordinary contrast between dark body markings and bright metallic coloration.

Color Phases

Temensis is particularly interesting because it can undergo major changes in appearance during its development and reproductive cycle.

This makes watching a specimen mature one of the most rewarding aspects of keeping the species.

Natural Habitat and Origin

Cichla temensis originates from Amazonian and Orinoco-related freshwater systems in northern South America, particularly blackwater and clearwater environments.

Wild fish inhabit rivers, lagoons, flooded forests, and other productive freshwater habitats where they hunt smaller fish.

Their natural environment helps explain their preference for:

• Warm water
• Excellent oxygenation
• Strong filtration
• Swimming space
• Cover and structure
• High-quality food

Aquarium Setup

Keeping Cichla temensis successfully requires planning for its adult size.

Recommended Tank Size

A young Temensis can initially be maintained in a suitably sized growing aquarium, but an adult requires a very large aquarium.

For long-term adult care, a 300-gallon aquarium or larger is strongly recommended, with even larger systems being preferable for big specimens or groups.

A large footprint is especially valuable because Peacock Bass are active swimmers.

Substrate

Sand or smooth gravel works well.

A natural-looking substrate also complements the fish’s South American appearance.

Decorations

Use sturdy aquarium décor such as:

• Large driftwood
• Smooth rocks
• Large roots
• Artificial plants
• Heavy aquarium structures

Avoid fragile decorations that can be moved or broken by a powerful adult fish.

Leave plenty of open swimming space.

Water Parameters

Maintain clean, stable, well-oxygenated freshwater.

Recommended parameters:

• Temperature: 76–82°F (24–28°C)
• pH: approximately 6.0–7.5
• Hardness: Soft to moderately hard
• Ammonia: 0 ppm
• Nitrite: 0 ppm
• Nitrate: preferably maintained at low levels

Temensis can adapt to a reasonable range of water conditions, but stability and water quality are extremely important.

Large predatory fish generate substantial waste, making filtration and regular water changes essential.

Filtration and Aquarium Maintenance

Heavy Filtration

A large Cichla temensis requires serious filtration.

Consider using:

• Large canister filters
• Powerful sump filtration
• Multiple filtration stages
• Strong biological filtration
• Mechanical pre-filtration

Oversizing filtration is often beneficial when keeping monster fish.

Water Changes

Regular partial water changes help control nitrate and dissolved organic waste.

A heavily stocked predator aquarium may require more frequent maintenance than a lightly stocked community aquarium.

Strong surface agitation and adequate circulation should also be maintained to support oxygen levels.

Diet and Feeding

Temensis is a predatory carnivorous cichlid.

Recommended Diet

A high-quality predator diet can include:

• Large carnivore pellets
• High-quality cichlid pellets
• Frozen shrimp
• Mysis shrimp
• Krill
• Appropriate frozen seafood
• Other nutritionally balanced prepared foods

Fish should not rely exclusively on feeder fish.

Feeding Juveniles

Young specimens can be fed appropriately sized foods several times throughout the day depending on their size and growth requirements.

Feeding Adults

Larger fish generally require fewer meals than juveniles. Feed enough to maintain healthy growth without excessive fat accumulation or unnecessary water pollution.

A varied, nutritionally complete diet is preferable to simply feeding large quantities.

Behavior and Temperament

Active Predator

Cichla temensis is an active predator that spends considerable time exploring the aquarium.

It may rapidly accelerate across the tank when feeding, making it an exciting species to watch.

Territorial Behavior

Adults can become territorial, particularly during breeding.

The species is therefore best suited to aquarists with experience maintaining large predatory cichlids.

Feeding Response

Temensis often develops an impressive feeding response and may quickly learn to associate the aquarist with feeding time.

Tank Mates

Selecting tank mates requires considerable care.

Potential Tank Mates

In a sufficiently large aquarium, compatible large fish may include:

• Other appropriately sized Peacock Bass
• Large South American cichlids
• Large plecos
• Large catfish
• Other robust predator species

However, compatibility depends heavily on individual temperament and relative size.

Important Predator Rule

Anything small enough to fit inside the mouth of an adult Temensis may potentially become food.

Do not select tank mates simply because they appear peaceful. Size, temperament, swimming behavior, and aquarium dimensions all matter.

Growth and Adult Size

Cichla temensis is a large species and should never be purchased without planning for its adult requirements.

Growth can be influenced by:

• Genetics
• Feeding
• Water quality
• Temperature
• Aquarium size
• Stress
• Overall husbandry

Providing excellent conditions during the juvenile stage helps support healthy development.

Breeding

Temensis is a fascinating breeding species for experienced aquarists.

During reproductive periods, mature fish may become significantly more territorial and develop stronger coloration.

A breeding pair may select and defend a suitable spawning site, with parental behavior continuing after spawning.

Breeding large Peacock Bass requires substantial aquarium space and careful management of aggression.
