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