RED TIGER SEVERUM CICHLID

The Red Tiger Severum, also known as Tiger Severum, Curare Severum, Cichlasoma severum, Heros Severus ‘curare’, Heros Severus “Rio Curare,” is now officially described as true Heros Severus. The scientific name ‘curare’ or “Rio Curare” was derived from the location where they are found.

The Red Tiger Severum is a tropical freshwater fish that originates from the upper Rio Negro basins in South America. This species has historically been confused with its relatives, the most notable being the Heros liberifer.

Both of these two species are uncommon in the aquarium trade. Instead, they are commonly traded as Heros efasciatus and Heros sp. Rotkeil. The former is the most sought after and readily available species in the hobby, while the latter is tank-bred color morphs and has not been scientifically described.

Lifespan

The average Red Tiger Cichlid lives for around 10 years.

It can be a bit tricky to determine the age of fish. In the wild, their lifespan may be shorter due to predation and environmental factors.

In captivity, Red Tiger Severums can live longer if they are provided with the proper care. There are several factors that contribute to their longevity. To help them reach their full potential, you’ll need to provide them with a large tank, high-quality water, and a nutritious diet.

Size & Growth Rate

The Red Tiger Severum (Heros Severus) reaches a maximum size of about 11 inches (28 cm) when fully grown. 

Red Tiger Severums are not particularly fast-growing fish, and it can take up to 2-3 years for them to reach their full size. 

Like any other fish, the growth rate depends on their purchase size and age, as well as if their growth has been stunted due to poor water conditions and food. 

Red Tiger Severums are wild-caught fish and sold as juveniles without being dewormed. They may not grow faster than other Severums because the parasites and worms will interfere with their growth.

Red Tiger Severum Tank Size

If you are looking to keep a large and vibrant Red Tiger Severum, then a large tank is absolutely essential. These majestic creatures are among the largest of their species, and they require a massive tank with ample room to swim and explore.

Our recommended minimum tank size for a single adult Red Tiger Severum is 75 gallons (48″ x 18″ x 21″). If you’re planning on owning a pair, you should get a tank that will hold at least 125 gallons.

Water Parameters

Water parameters are critical to Red Tiger Severum’s health. In their natural habitat, Red Tiger Severums inhabit blackwater rivers with very specific water parameters.

In the aquarium, it is important to replicate these water conditions as closely as possible. That means you must stay within the following parameters.

• Water temperature: 75°F to 82°F
• pH levels: 5.0 to 6.5
• Water hardness: 0 to 6 dH
• Ammonia: 0ppm
• Nitrite: 0ppm
• Nitrate: <30ppm

Décor and Plants

These fish do best with a sandy substrate. Rocks and bogwood can create hiding spaces and “barriers,” which is helpful for managing aggression.

The natural bogwood will safely lower the pH levels, shelter other aquatic creatures, and give off the authentic riverbed look.

Live plants are not necessary due to their natural habitat, but if you are looking to create a more natural and scenic look in your Red Tiger Severum’s tank, there is a variety of plants that you can use.

Red Tiger Severum Diet

The Red Tiger Severum is not a fussy eater and will accept the most common aquarium foods. They are particularly fond of live and frozen foods such as bloodworms, brine shrimp, earthworms, and mosquito larvae. They will also consume pellets, flakes, and granules designed for omnivores.

It is important to offer a variety of foods to ensure they receive the nutrients they need. Feed them 2-3 times per day in small amounts that can be consumed within a few minutes. Remove any uneaten food to prevent water quality issues.
