Severum Green Cichlid: An In-Depth Guide to Its Care and Captivation

Introduction

The Severum Green Cichlid (Heros severus) is a captivating freshwater fish native to the Amazon River Basin in South America. Renowned for its emerald-green coloration, peaceful demeanor, and relatively easy care requirements, this species has gained immense popularity among hobbyists. This comprehensive article delves into all aspects of Severum Green Cichlid care, from habitat setup and feeding to breeding and troubleshooting common mistakes.

Taxonomy and Description

The Severum Green Cichlid belongs to the family Cichlidae and the genus Heros. It is one of the most common species kept in aquariums, with its green coloration being the primary attraction. The fish can grow up to 8 inches in length, with males typically larger than females. Their body shape is robust, with a rounded back and a laterally compressed body.

Natural Habitat and Distribution

Severum Green Cichlids inhabit the slow-moving, blackwater rivers and streams of the Amazon River Basin. These waterways are characterized by soft, acidic water with an abundance of vegetation and submerged wood. In their natural environment, they feed primarily on insects, small fish, and plant matter.

Aquarium Setup

Tank Size: A minimum tank size of 55 gallons is recommended for a single Severum Green Cichlid, with larger tanks required for multiple fish.

Water Parameters:
* Temperature: 75-86°F (24-30°C)
* pH: 5.0-7.5
* Hardness: 0-15 dGH

Substrate: Gravel or sand is suitable, but natural substrates such as Amazonia soil or crushed coral sand can help to maintain the ideal pH and hardness levels.

Filtration: A powerful canister filter is essential for maintaining water quality, as Severum Green Cichlids are known to produce a significant amount of waste.

Decoration: Provide plenty of hiding places using driftwood, plants, and caves. Live plants are recommended, as they contribute to the aquarium's ecosystem and provide cover for fry.

Feeding

Severum Green Cichlids are omnivorous, accepting a wide variety of food. A well-balanced diet should include:
* High-quality commercial cichlid pellets
* Live or frozen foods (e.g., brine shrimp, bloodworms, tubifex worms)
* Vegetables (e.g., zucchini, spinach, peas)
* Fruit (e.g., banana, apple)

Feed your Severum Green Cichlid twice a day, in amounts that can be consumed within a few minutes. Avoid overfeeding, as this can contribute to health issues.

Behavior and Temperament

Despite their imposing appearance, Severum Green Cichlids are generally peaceful and non-aggressive towards other fish. However, they can become territorial during breeding and may exhibit aggression towards smaller or more timid tankmates. They are often kept in community tanks with other South American cichlids, such as Angelfish or Discus.

Breeding

Severum Green Cichlids can be relatively easy to breed in captivity if provided with the right conditions.
* The male establishes a nesting site by digging a depression in the substrate.
* The female deposits her eggs on the cleaned surface, with the male fertilizing them.
* The eggs hatch within 2-3 days, and the fry remain in the nest under parental care.
* After 1-2 weeks, the fry free-swim and can be fed newly hatched brine shrimp or baby fish food.

Tips and Tricks

• Provide a varied diet: Offer a diverse menu to ensure your Severum Green Cichlid receives all the essential nutrients.
• Maintain water quality: Regular water changes are crucial to prevent health problems and prolong your fish's lifespan.
• Limit interaction: Avoid handling the fish unnecessarily, as they can become stressed and may lose their coloration.
• Offer hiding places: Provide ample caves and plants to reduce aggression and provide a sense of security.

Common Mistakes to Avoid

• Overcrowding: Avoid placing too many fish in a small tank, as this can lead to aggression and health issues.
• Overfeeding: Feeding too much can contribute to obesity, digestive problems, and reduced lifespan.
• Ignoring water parameters: Maintaining the correct pH, temperature, and hardness levels is essential for the well-being of your fish.
• Introducing aggressive tankmates: Avoid placing Severum Green Cichlids with overly aggressive or territorial species that may threaten them.
• Ignoring health signs: Observe your fish regularly for any signs of disease or stress, and seek veterinary attention promptly if necessary.
