When was Synodontis nigrita first described?

It was first described by French zoologist Achille Valenciennes in 1840. The type specimen is in the Muséum National d’ Histoire Naturelle de Paris. Like all members of the genus Synodontis, S. nigrita has a strong, bony head capsule that extends back as far as the first spine of the dorsal fin.

What does Synodontis nigrita look like?

Like all members of the genus Synodontis, S. nigrita has a strong, bony head capsule that extends back as far as the first spine of the dorsal fin. The head contains a distinct narrow, bony, external protrusion called a humeral process.

Synodontis nigrita, known as the false upside down catfish, is a species of upside-down catfish that occurs widely in northern Africa. It was first described by French zoologist Achille Valenciennes in 1840.

Do inverted catfish live upside down?

“To an inverted catfish, the water’s surface is just another substrate,” she says. But in the vast majority of cases, says Love, “there’s no selective advantage for most fishes to be upside down.” The answer, as Wainwright says, is likely that for most fish, switching simply isn’t worth it.

Can catfish live in a pond in winter?

They most assuredly can. I have raised thousands of catfish, many of which were kept in ponds in the Winter where temperatures reached lows in the high 30 degree Fahrenheit range. But catfish require much warmer water during part of the year if they are to reproduce. Channel catfish spawn when the water is in the mid 70s.

Do catfish need warm water to reproduce?

But catfish require much warmer water during part of the year if they are to reproduce. Channel catfish spawn when the water is in the mid 70s. So if catfish were introduced into water where the spawning temperature is never achieved, they would live, grow old and die, but never reproduce.

Not much is known about the reproduction in these fish. It has been determined that July to October is when they spawn and that they swim in pairs during this spawning time. Species of Synodontis have been noted to reproduce with the flooding period of the rainy season. Synodontis nigriventris is a popular aquarium fish.

Valentine Synodontis/Synodontis “valentiana”: This name is often applied to a S. decora /S. multipunctata hybrid.

When did Synodontis evolve in Africa?

A recent study on the molecular phylogeny of Synodontis found that those in Lake Tanganyika evolved as recently as 5.5 million years ago, and that a group of closely-related southern African species is even younger, evolving within the last 900,000 years or so.

What are the characteristics of Synodontis?

All species in the genus Synodontis have a hardened head cap that has attached a process (humeral process) which is situated behind the gill opening and pointed towards the posterior. The dorsal fin and pectoral fins have a hardened first ray which is serrated. Caudal fin is always forked.

How many species of Synodontis are there in the world?

There are currently 131 recognized species in this genus: Synodontis accounts for about one-quarter of African catfish species.

Synodontis nigriventris are mostly nocturnal, and feed on insects, crustaceans, and plant matter. These fish lay eggs. The young fish do not swim upside-down until they are about two months old.

What is the lifespan of Synodontis nigriventris?

In captivity, the changeling lives no longer than 10 years. Due to its small size, an aquarium with a volume of 50 liters or more is enough to keep a pair of Synodontis nigriventris. The water parameters in it should be as follows:

Do Synodontis nigriventris lay eggs?

Synodontis nigriventris are mostly nocturnal, and feed on insects, crustaceans, and plant matter. These fish lay eggs. The young fish do not swim upside-down until they are about two months old. Adults swim and rest upside down in the water.

How big does a mud catfish get?

Like all catfish species, whisker-like barbels surround the mouth of the mud catfish. Mud cats can grow in length to 3 to 4 feet and can weigh more than 100 lbs. The preferred habitat of mud cats are deep pools of lakes, rivers, streams, canals and reservoirs, especially where the water current is slow with a cloudy or turbid quality.

When is the best time to catch mud catfish?

Anglers are most successful in catching mud catfish during their spawning season when the water temperature is between 75 and 80 degrees Fahrenheit. Mud catfish, also commonly referred to as flathead catfish, is one of the most coveted catfish species.

Are Mud Catfish good to eat?

Mud catfish, also commonly referred to as flathead catfish, is one of the most coveted catfish species. They are good to eat and are considered invasive at times because they can cause decline in other fish species. Anglers can catch mud cats using a variety of live baits, including bluegill, common carp, bullhead and green sunfish.

How long do fish live outside of water?

On average, fish can live about 10 minutes outside of water but can die faster if they land on an absorbent surface. However, saltwater fish will often live longer, and certain fish, like amphibious fish, have particular adaptations that enable them to last for a long time outside of the water.

Is Synodontis being bred bred in captivity?

Most species of medium/large Synodontis can be sexed using this method but it should be noted that most species take 2 years or more to reach sexual maturity. Unsure. It definitely is being bred bred in captivity but it is unclear as to whether this is by natural methods or on fish farms via the use of hormone injections.

When did Synodontis first appear in East Africa?

The earliest fossils of Synodontis in East African are from the Early Miocene. Many Synodontis fossils are the spines because they are very sturdy and so they are preserved better. The fossils of spines that are found are used to determine the family or genera of the fish but it cannot determine the species.

Are Synodontis catfish easy to keep up with?

Synodontis Catfish are straightforward to keep up as they readily settle for nearly any number of meals supplied, greedily perusing the tank ground for something edible. So long as the water’s high quality is maintained they have an inclination to thrive.

What are the characteristics of Synodontis nigrita?

Contaminants often include S. nigriventris and small juveniles of many West African Synodontis species. S. nigrita has a dark gray background with black spots on the body and fins, giving it a ”lace-like” appearance, hence the common name: ”lace catfish”.
