Predators UnusualConservation status: Near threatened NT

Family:Polypteridae (Bichirs)

Other scientific names: Calamichthys calabaricus, Calamoichthys calabaricus, Calanichthys calabaricus, Erpetoichthys calabaris, Erpetoichthys robbianus, Herpetoichthys calabaricus

The scientific name Erpetoichthys calabaricus belongs to the family Polypteridae, known as the bichirs, and denotes the species known as the Reedfish or Ropefish. These amazing fish are the closest relatives of the Polypterus. Both species represent the last surviving members of ancient fish whose history spans millions of years, dating back to the dinosaur era in the Triassic period. The oldest fossils found indicate an age of over 200 million years.

Frequently asked questions

The essentials: size, tank volume, water parameters and care

How big does Reedfish get?

An adult reaches 30 cm in length. Plan the tank around the maximum size: the fish quickly outgrows a cramped setup.

What size aquarium does Reedfish need?

The minimum recommended volume is 500 L. A smaller tank speeds up nitrate build-up and raises stress levels.

What water parameters does Reedfish need?

Temperature 23–30 °C, pH 6–7.5, hardness 5–20 dGH. Stability matters more than exact values: sudden swings are harder on the fish than a small deviation from the ideal.

How long does Reedfish live?

Around 20 years when kept properly. Lifespan depends directly on tank volume, water quality and a varied diet.

Is Reedfish aggressive?

Temperament: semi-peaceful (including aggression during spawning / intraspecific conflicts). This is a predatory species — any fish small enough to fit in its mouth will eventually be eaten.

How many Reedfish should be kept together?

Recommended setup: both solitary and in group (flexible). Ignoring this is a common cause of stress and disease.

What does Reedfish eat?

Diet type: meat / protein (live, frozen, fresh). Feed small portions that are finished within a couple of minutes — overfeeding does more harm than underfeeding.

What is the scientific name of Reedfish?

The scientific name of the species is Erpetoichthys calabaricus, family Polypteridae (Bichirs). It also appears in the literature as: Calamichthys calabaricus, Calamoichthys calabaricus, Calanichthys calabaricus.
