Freshwater Barracuda
Ctenolucius hujeta
The Freshwater Barracuda, or Hujeta Pike Characin, is an elongated, torpedo-shaped ambush predator. It primarily inhabits the upper water levels. Though peaceful with fish too large to swallow, it is a highly efficient piscivore and will readily consume smaller tank mates like Tetras or Guppies. Known to be skittish and prone to fatal jumping, a tight-fitting lid is strictly required.

Freshwater Barracuda Varieties
Each variety inherits the species defaults above. Only differences are highlighted.
Standard Adult
Adult size. While relatively inactive compared to other large characins, their sudden ambush strikes require significant open surface space. Completely peaceful with large-bodied, bottom-dwelling tank mates.
Differs in 1 trait from base species
Also known as: Adult, Full Grown
Juvenile (Grow-out)
Young Hujeta Pikes are often sold around 3-4 inches. They grow rapidly and have high metabolisms, being highly predatory towards small fish even at this stage. Will quickly outgrow starter aquariums.
Differs in 4 traits from base species
Also known as: Baby, Juvenile
Freshwater Barracuda Care Guide Summary
The Freshwater Barracuda, scientifically known as Ctenolucius hujeta, belongs to the Characins family group. Adults reach a maximum size of approximately 25 cm and have a fusiform body shape with a moderate growth rate. Classified as semi-aggressive, this species primarily occupies the surface zone of the aquarium and produces a high level of biological waste.
To thrive, the Freshwater Barracuda requires a freshwater only aquarium with a minimum volume of 250 litres and a tank length of at least 120 cm. Water temperature should be maintained between 22°C and 28°C, with a pH range of 6–7.5 and a general hardness of 5–15 dGH. A moderate water flow is preferred.
The Freshwater Barracuda is a rewarding species to keep, provided its core environmental needs are met. This species is available in 2 varieties: Standard Adult and Juvenile (Grow-out). Each may differ slightly in size, temperament, or care needs, so it is worth checking the specific requirements of the variety you plan to keep.
Freshwater Barracuda Habitat Setup
When setting up an aquarium for the Freshwater Barracuda, a moderate water flow best suits their natural preferences. Because this species occupies the surface zone, the aquarium layout should prioritise adequate surface area with floating cover to make them feel secure near the waterline. Useful additions include floating plants to diffuse overhead light and create shaded areas. Keepers should note that a tight-fitting lid is essential, as this species is a known jumper.
Freshwater Barracuda Compatibility Notes
Classified as semi-aggressive, the Freshwater Barracuda is adaptable and can be kept singly or in a small group, offering flexibility when planning a community tank. When choosing tankmates, any fish small enough to fit in its mouth will likely be eaten and boisterous or fast-moving tankmates may cause this species undue stress. Selecting tankmates that favour different water layers from the surface zone can help reduce competition and territorial overlap.
Who Freshwater Barracuda Is Actually For
Freshwater Barracuda is best for a fishkeeper who wants a species that can settle into a calmer community setup and can provide someone who understands its individual space requirements. It makes the most sense for a hobbyist who will actually build around its needs, especially plants.
The most common mistake is buying Freshwater Barracuda for looks first and only later discovering how its adult size, behavior, or bioload changes the whole tank plan. Another frequent problem is forcing it into an over-busy community when it would do better with more room or more deliberate tankmate choices.

Fish Similar to Freshwater Barracuda
Red Tail Barracuda
Acestrorhynchus falcatus
A fast-moving, torpedo-shaped predator native to the Amazon and Orinoco basins. Despite the name, it is a characin, not a true marine barracuda. It is strictly piscivorous (eats other fish) and requires a large, long aquarium with high flow and a tight-fitting lid due to its tendency to jump when startled. Highly predatory but can be skittish if kept with aggressive or overly boisterous tankmates.
African Pike
Hepsetus odoe
The African Pike is a formidable and fascinating predatory fish native to West and Central Africa. With its elongated, torpedo-shaped body and a mouth full of prominent sharp teeth, it is a surface-dwelling ambush predator that requires a massive aquarium. Best kept by advanced aquarists, they are heavily piscivorous and will consume any fish that fits in their mouths, though they are generally tolerant of similarly sized, robust tank mates.
Pike Cichlid (Xingu)
Crenicichla sp. Xingu
A massive, highly intelligent, and aggressive predatory cichlid native to the fast-flowing clear waters of the Rio Xingu basin. Characterized by their elongated, torpedo-like bodies and huge mouths, they are formidable ambush predators. Due to their immense size (often exceeding 14 inches) and extreme territorial nature, they require massive aquariums with heavy filtration. They are highly intolerant of conspecifics unless kept as a confirmed bonded pair.
Three-Spot Torpedo Hap
Exochochromis anagenys
A striking, large predatory haplochromine cichlid endemic to Lake Malawi. Known for its torpedo-shaped body (fusiform), it is an open-water hunter that preys on smaller fish like mbuna. While highly predatory and requiring a massive tank, they are relatively mild-mannered toward tankmates too large to be swallowed. Conspecific males, however, are violently intolerant of one another.
Spotted Headstander
Chilodus punctatus
A unique, peaceful South American characin known for swimming at a distinct 45-degree, head-down angle. They are highly social, somewhat skittish shoaling fish that thrive in mature, densely planted aquariums. They actively graze on algae and biofilm across surfaces and leaves, though they do not eat ornamental plants. They require stable water parameters and should only be added to mature tanks.
Siamese Algae Eater
Crossocheilus oblongus
Famous for being one of the few freshwater fish that actively consumes Black Beard Algae (BBA). A torpedo-shaped, active bottom-to-midwater swimmer native to Southeast Asian streams. True Siamese Algae Eaters feature a distinct black horizontal stripe that extends all the way through the tail fin. As they mature, they can become lazy, preferring prepared foods over algae, and may occasionally chase other bottom dwellers.
