Polypterus Bichir Lapradei
Polypterus bichir lapradei
The Lapradei Bichir is a massive, ancient, air-breathing predatory fish native to West Africa. Featuring distinct dorsal finlets and a heavily armored, snake-like body, it is a fascinating 'monster fish'. As nocturnal ambush predators, they will consume any tank mate that fits in their surprisingly large mouths. However, they are remarkably peaceful with robust companions that are too large to eat. A tight-fitting lid is absolutely mandatory as they are notorious escape artists.

Polypterus Bichir Lapradei Varieties
Each variety inherits the species defaults above. Only differences are highlighted.
Adult (Standard)
Fully grown Lapradei Bichirs are true monster fish, reaching up to 30 inches (75cm). They require massive enclosures with extensive floor space, fine sand substrate, and highly efficient filtration systems to handle their extreme bioload.
Same care requirements as the base species
Also known as: Adult, Giant Bichir
Juvenile (Grow-out)
Sold at smaller sizes, juveniles grow extremely fast during their first year. While they can be temporarily housed in a smaller grow-out tank (150L+), they will require rapid upgrades to a massive system.
Differs in 5 traits from base species
Also known as: Baby Bichir, Juvenile
Polypterus Bichir Lapradei Care Guide Summary
The Polypterus Bichir Lapradei, scientifically known as Polypterus bichir lapradei, belongs to the Oddballs family group. Adults reach a maximum size of approximately 75 cm and have a eel body shape with a moderate growth rate. Classified as semi-aggressive, this species primarily occupies the bottom zone of the aquarium and produces a extreme level of biological waste.
To thrive, the Polypterus Bichir Lapradei requires a freshwater only aquarium with a minimum volume of 680 litres and a tank length of at least 180 cm. Water temperature should be maintained between 24°C and 28°C, with a pH range of 6.5–8 and a general hardness of 5–20 dGH. A low water flow is preferred.
Due to its specialist needs, the Polypterus Bichir Lapradei is best suited for fishkeepers who can provide a carefully planned setup. This species is available in 2 varieties: Adult (Standard) 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.
Polypterus Bichir Lapradei Habitat Setup
When setting up an aquarium for the Polypterus Bichir Lapradei, a low water flow best suits their natural preferences. Because this species occupies the bottom zone, the aquarium layout should prioritise sufficient floor space with hiding spots among rocks, wood, or dense planting. Useful additions include a sand substrate to accommodate their sifting behaviour, smooth gravel or rounded substrate to protect their sensitive barbels, and driftwood, which can serve as both a hiding place and a dietary supplement. Keepers should note that a tight-fitting lid is essential, as this species is a known jumper.
Polypterus Bichir Lapradei Compatibility Notes
Classified as semi-aggressive, the Polypterus Bichir Lapradei 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. Selecting tankmates that favour different water layers from the bottom zone can help reduce competition and territorial overlap.
Who Polypterus Bichir Lapradei Is Actually For
Polypterus Bichir Lapradei 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 sand.
The most common mistake is treating Polypterus Bichir Lapradei like any other community fish and skipping the soft sand it needs to forage safely. Another frequent problem is forcing it into an over-busy community when it would do better with more room or more deliberate tankmate choices.

Polypterus Bichir Lapradei Feeding & Diet Considerations
The Polypterus Bichir Lapradei is a predatory species that will readily consume small fish, so nano or bite-sized tankmates should be avoided and is primarily active at dusk and dawn, so offering food shortly after lights-off ensures it receives adequate nutrition.

Fish Similar to Polypterus Bichir Lapradei
Congo Bichir
Polypterus endlicheri congicus
The Congo Bichir is a prehistoric-looking, bottom-dwelling monster fish and one of the largest species in the Polypteridae family. They are obligate air-breathers and ambush predators that will eagerly consume any tankmate small enough to fit in their surprisingly large mouths. Due to their massive adult size, they require extremely large custom aquariums, heavy filtration, and a tight-fitting lid to prevent escapes.
Delhezi Bichir (Armored Bichir)
Polypterus delhezi
An ancient, air-breathing predatory fish from the Congo River basin. Known for its distinct black vertical bands and dinosaur-like dorsal finlets. They are bottom-dwelling ambush predators with poor eyesight but an excellent sense of smell. While generally peaceful with similarly sized or larger fish, they are opportunistic piscivores and will eat anything that fits into their surprisingly large mouths.
West African Bichir
Polypterus retropinnis
An ancient, primitive fish with a snakelike body and a lung-like swim bladder that allows it to breathe atmospheric air. The West African Bichir is a nocturnal bottom-dweller that relies on an excellent sense of smell to hunt. While surprisingly peaceful towards large tankmates, it is highly predatory and will swallow any fish that fits in its mouth. It requires a tight-fitting lid as it is a notorious escape artist.
Weeksi Bichir
Polypterus weeksii
A prehistoric, heavily-armored predatory fish from the Congo River basin. Known for its distinctively large head, thick body, and prominent dorsal finlets. They possess functional lungs and must breathe atmospheric air. While peaceful toward fish too large to swallow, they are highly predatory and will consume anything that fits in their spacious mouths. They are notorious escape artists.
Saddled Bichir
Polypterus endlicheri
A massive, prehistoric-looking predatory fish native to Africa. Known for its prominent dorsal finlets, striking 'saddled' striping, and ability to breathe atmospheric air using a modified swim bladder. They are bottom-dwelling ambush predators. They are completely peaceful to fish too large to swallow, but highly predatory toward anything else. They must be kept on soft sand, as they swallow their prey whole and ingested gravel can be fatal.
Palmas Bichir
Polypterus palmas palmas
An ancient, primitive bottom-dweller from West Africa known for its dinosaur-like appearance and ability to breathe atmospheric air using modified lungs. While it is one of the smaller 'upper jaw' Bichir species, it is a highly capable ambush predator. It is generally peaceful towards fish too large to swallow, but completely unsafe for small community fish. A tight-fitting lid is absolutely mandatory to prevent escaping.
