Common Name: Freshwater Dolphin Fish

Scientific Name: Mormyrus cf. longirostris

Habitat and Distribution:

The Freshwater Dolphin Fish is a species of elephantfish native to freshwater habitats in West Africa. They are commonly found in rivers and tributaries with slow-moving water and sandy or muddy bottoms.

Size and Lifespan:

The Freshwater Dolphin Fish can grow up to 20 inches in length and has an average lifespan of 10-15 years.

Diet and Behavior:

Freshwater Dolphin Fish are carnivorous and primarily feed on small fish and invertebrates. They have a long snout that is used for detecting prey in the sand and mud at the bottom of the river.

In the aquarium, they should be fed a varied diet of frozen or live foods such as bloodworms, brine shrimp, and small pieces of fish. They are generally peaceful and can be kept with other non-aggressive fish, but may eat smaller fish.

Aquarium Care and Tank Requirements:

The Freshwater Dolphin Fish requires a spacious aquarium of at least 75 gallons. They are sensitive to poor water conditions, so a good filtration system is required to maintain high water quality. They prefer a sand substrate and some driftwood or rocks for hiding places.

The ideal water temperature range for this species is 72-82°F with a pH range of 6.5-7.5. They require a moderate water flow and a partially open top to allow for gas exchange.

Ideal Tank Mates:

Freshwater Dolphin Fish can be kept with other non-aggressive fish that are of similar size, but it's best to avoid keeping them with smaller fish that they may consider prey.

Difficulty Level:

The Freshwater Dolphin Fish is considered to be moderately difficult to keep and requires a well-maintained aquarium with stable water parameters.

Water Parameters:

• Temperature: 72-82°F
• pH: 6.5-7.5
• General Hardness (GH): 5-12 dGH
• Carbonate Hardness (KH): 2-10 dKH
• Ammonia: 0 ppm
• Nitrite: 0 ppm
• Nitrate: < 20 ppm

Additional Information:

• The Freshwater Dolphin Fish is named for its long snout, which resembles the beak of a dolphin.
• This species is sometimes referred to as the African Freshwater Dolphin.
• In the wild, Freshwater Dolphin Fish are known to use electrical impulses to communicate with each other and locate prey.
