Gold Severum Species Overview

Scientific Name

Heros efasciatus

Common Names

• Gold Severum
• Golden Severum
• Gold Hero Cichlid
• Golden Hero Cichlid
• Severum Cichlid

The name “Gold Severum” generally refers to a selectively bred color form of Heros, with the exact appearance varying between individual fish and strains.

Origin

Severums are South American freshwater cichlids associated with the Amazon and surrounding river systems.

Their natural environment typically features:

• Slow-moving water
• Vegetation
• Driftwood
• Leaf litter
• Soft substrates
• Sheltered areas

A natural aquarium setup can replicate these characteristics while providing plenty of open swimming space.

Gold Severum Appearance

Brilliant Golden Coloration

The Gold Severum is particularly valued for its warm yellow-to-golden body coloration.

Depending on the individual, coloration may range from pale yellow to rich gold.

Other characteristics include:

• Deep, laterally compressed body
• Rounded facial profile
• Long dorsal fin
• Long anal fin
• Yellow-gold scales
• Attractive fin coloration
• Darker markings that may become more noticeable with age

Adult coloration can become considerably more impressive than juvenile coloration.

Aquarium Setup

Recommended Tank Size

For a single adult Gold Severum, a 75-gallon aquarium or larger is recommended as a practical long-term starting point.

For a pair or community containing multiple large fish, consider 100 gallons or larger depending on stocking and compatibility.

The aquarium should have sufficient horizontal swimming space because Severums become substantial fish.

Substrate

Sand or smooth gravel works well.

Gold Severums may occasionally move substrate while exploring or feeding, so avoid sharp materials that could injure the fish.

Decorations

A South American-style aquarium can include:

• Driftwood
• Smooth rocks
• Aquarium-safe caves
• Hardy plants
• Floating vegetation
• Leaf litter
• Open swimming areas

Leave enough open space for the Severum to move comfortably throughout the aquarium.

Water Parameters

Gold Severums generally appreciate warm, stable, clean water.

Recommended parameters include:

• Temperature: 76–82°F (24–28°C)
• pH: approximately 6.0–7.5
• Ammonia: 0 ppm
• Nitrite: 0 ppm
• Nitrate: Keep low with regular water changes
• Hardness: Soft to moderately hard

Severums can adapt to a reasonable range of conditions, but stability and excellent water quality are essential.

Gold Severum Feeding

Gold Severums are omnivorous and should receive a varied, nutritious diet.

Recommended Foods

A quality diet can include:

• High-quality cichlid pellets
• Floating pellets
• Sinking pellets
• Cichlid flakes
• Spirulina-based foods
• Frozen brine shrimp
• Frozen bloodworms
• Mysis shrimp
• Vegetable-based foods

Plant matter is particularly useful as part of a balanced diet.

Feeding Juveniles

Smaller Severums should receive appropriately sized foods that are easy to consume.

Feed moderate portions and avoid overfeeding. As the fish grows, gradually increase pellet size.

A varied diet can help support healthy growth and strong golden coloration.

Behavior and Temperament

Gold Severums are generally considered peaceful to moderately territorial for their size.

They are often considerably less aggressive than many large Central American cichlids.

However, mature fish may become territorial, especially:

• During spawning
• When defending a preferred area
• When kept in a small aquarium
• When housed with incompatible tank mates

They are intelligent and interactive fish that can learn to recognize their keeper and quickly become a centerpiece of the aquarium.

Gold Severum Tank Mates

Compatible tank mates should be similarly sized and reasonably peaceful.

Potential choices can include:

• Other Severums
• Geophagus
• Larger peaceful South American cichlids
• Angelfish
• Larger peaceful tetras
• Medium-to-large catfish
• Plecos
• Certain peaceful knifefish

Avoid extremely aggressive fish as well as tiny fish that may be viewed as food.

Individual temperament should always be considered.

Gold Severum and Plants

Severums can be challenging with live plants because they may nibble vegetation, uproot plants, or disturb the substrate.

If keeping plants, choose hardy species and secure them properly.

Options may include:

• Anubias
• Java fern
• Vallisneria
• Other robust aquarium plants

Floating plants can also provide shade and cover without being as easy for the fish to uproot.

Growth and Color Development

One of the most enjoyable aspects of keeping a Gold Severum is watching its appearance develop.

Juvenile Stage

Young fish may have less intense golden coloration and a slimmer body.

With good nutrition and proper aquarium conditions, the fish gradually develops its characteristic deep-bodied adult appearance.

Adult Coloration

Mature Gold Severums can display:

• Rich golden-yellow coloration
• Metallic scale highlights
• Stronger facial coloration
• Deep body proportions
• More developed fins

Genetics play a major role in the final appearance of each specimen.

Filtration and Aquarium Maintenance

Gold Severums produce a significant amount of waste as they grow, so strong filtration is important.

Recommended Filtration

Consider:

• Oversized canister filters
• Sump filtration
• Strong biological filtration
• Efficient mechanical filtration
• Good oxygenation

Regular water changes should be part of the maintenance routine.

Keep mechanical filtration clean and monitor ammonia, nitrite, and nitrate regularly.

Breeding Gold Severums

Gold Severums can form pairs and breed in suitable aquarium conditions.

When preparing to spawn, a pair may select and clean a flat surface such as:

• A rock
• Driftwood
• Aquarium decoration
• Flat substrate area

Breeding behavior can result in increased territoriality.

If breeding is successful, parents may guard the spawning area and defend eggs or fry from other aquarium inhabitants.
