Do banjo catfish need to be in groups?

How many species of banjo catfish are there?

Banjo catfish consist of 43 species. Their phylum is Chordata, which consists of well-known vertebrates such as other fish, birds, and mammals. These fish consist of 43 different species, all known for their unique body shape and small size. All banjo catfish dominate South American countries such as Brazil, Uruguay, and Bolivia.

Do banjo catfish have adipose fin?

But Banjo Catfish do not have an adipose fin and they lack the locking mechanism on their dorsal spine that is common in most species of catfish. Due to its small size, it has numerous potential predators. To make up for this they have extremely advanced camouflage that literally makes them disappear into the debris of their natural habitat.

Do banjo catfish play dead?

Yes, the banjo catfish does play dead, lying still at the bottom of the aquarium, not moving at all. These fish adopt this technique as a part of their defense mechanism to save themselves from predators. Q. Can banjo catfish live in brackish water?

Do catfish species with adipose fin have different habitats?

This time they consider 1906 catfish species, and compared the presence of the adipose fin to the habitat in which the species lived.   They found that for species in moving waters (streams and rivers), an adipose fin was more often present than for species in low-flow environments, such as lakes.

Can banjo catfish live with other fish?

Banjo Catfish are moderately hardy and can adjust to a variety of aquarium conditions. They can be kept as singly or as a group and are very peaceful fish, desirable in any community aquarium. They are compatible with all sizes of community fish, even the smallest of tank mates.

What kind of fin does a white catfish have?

As with the other large catfish species, white catfish have the adipose fin and the single, often serrated spine in the dorsal and pectoral fins. White catfish are bluish-gray on their back and sides and white underneath.

What fish have adipose fins?

The catfish (here, flathead) is another group of fish exhibiting an adipose fin, particular for those species in moving waters. (Source: Tennessee Wildlife Resources Agency)

Do catfish have scales or spines?

Instead of scales, catfish have spines in the front of their fins and also fleshy and ray-less posterior fin which is called an adipose fin. One of their most notable physical features is, of course, their slender and prominent whisker-like barbels that gave them this unique name in the first place.

How can you tell a white catfish from channel catfish?

It usually has numerous dark spots on the body, except in older individuals and spawning males.The surest way to identify the white catfish is to count the rays in the anal fin. The white catfish has 19-23 rays and the fin is rounded along the bottom edge. The channel catfish has 24-30 rays and also has a rounded anal fin.

Do salmon have adipose fins?

Close-up of adipose fin on salmonid species. ( Source) As a natural extension of their fin-clipping comparisons, Temple and Reimchen followed up in 2008 by investigating catfish, another fish group exhibiting an adipose fin.

What are adipose spines in fish?

In some species these spines are associated with poison glands which increases their effectiveness. An adipose fin is a small fin without any strengthening rays, that is only found in a few groups of fish such as the Myctophidae, Osmeridae and Salmonidae as well as some catfish.

What is an adipose fin?

The Adipose Fin: Old Mysteries with New Answers. If you are a fish, your fins are obviously critical for making a living. Fins provide a long list of essential functions, from generation of movement to stabilization, turning, stopping, and dynamic lift (to name a few).

Why does a catfish have a flat head?

A flattened head allows for digging through the substrate as well as perhaps serving as a hydrofoil. Some have a mouth that can expand to a large size and contains no incisiform teeth; catfish generally feed through suction or gulping rather than biting and cutting prey.

Do catfish have scales on their body?

Catfish do not have scales; their bodies are often naked. In some species, the mucus -covered skin is used in cutaneous respiration, where the fish breathes through its skin. In some catfish, the skin is covered in bony plates called scutes; some form of body armor appears in various ways within the order.

Do all catfish have a leading spine?

All catfish, except members of Malapteruridae (electric catfish), possess a strong, hollow, bony leading spine-like ray on their dorsal and pectoral fins.

How can you tell if a catfish is large or small?

The larger catfish spines are typically dull and they’re also larger as well (the tips of these spines in smaller fish are often like needles but in larger fish the spines are blunt). Smaller catfish are what you’ve got to watch for and be careful with, especially the really small ones.

What are fin-clipped salmon and steelhead?

In order to provide salmon & steelhead fishing opportunities, WDFW and the Tribes have marked salmon & steelhead by clipping the adipose fin (a small fatty fin directly behind the dorsal fin). In areas designated “release wild “, fin-clipped salmon and steelhead are the only fish that may be retained.

How many pairs of Fins does a salmon have?

• Fins: Salmon have two sets of paired fins (pelvic and pectoral) and four single fins (dorsal, caudal, anal, and adipose). Except for the adipose and caudal fins, the others are used basically to maneuver and balance the fish in the water. The adipose is a small, fleshy fin which serves no known purpose.

Why is the adipose fin called adipose?

Diagram of fish fins, including the adipose fin. ( Source: L.A. Walford) *Because the adipose fin is not rayed and appears as a unsupported finlet, one early hypothesis was that the fin stored fat, or adipose tissue. Studies have generally confirmed that the fin does not hold adipose, yet the name stuck.

What is the difference between adipose fin and Adipose spine?

Spines, when held stiff, make small fish much harder to swallow. In some species these spines are associated with poison glands which increases their effectiveness. An adipose fin is a small fin without any strengthening rays, that is only found in a few groups of fish such as the Myctophidae, Osmeridae and Salmonidae as well as some catfish.

How many spines does a fish have on its dorsal fin?

• Heavy-, deep-bodied • 8-9 spines in anterior dorsal fin; 2 spines in anal fin (one small, other large) • Lateral line extends well onto rounded caudal fin • Yellow/silver with green/brown back.

What is the adipose fin?

The adipose fin is a soft, fleshy fin found on the back behind the dorsal fin and just forward of the caudal fin. It is absent in many fish families, but found in nine of the 31 euteleostean orders (Percopsiformes, Myctophiformes, Aulopiformes, Stomiiformes, Salmoniformes, Osmeriformes, Characiformes, Siluriformes and Argentiniformes).

How much does the adipose fin increase caudal amplitude?

They found an 8% increase (on average) in caudal fin amplitude (i.e. work) in the fish without the adipose fin. Although they didn’t get into the mechanisms of how the fin possibly increases swimming efficiency, they did suggest that the adipose fin may create vortices that impact the caudal fin, or the fin may serve as a pre-caudal sensor to flow.

Can catfish breathe through their skin?

Some species of catfish are able to breathe through their skin, which is why most species of catfish are lacking scales and have smooth, mucus covered skin. Catfish are one of a few fish that have an organ called the Weberian apparatus that they use to communicate with each other underwater.

Do all catfish have a leading Ray?

All catfish, except members of Electric Catfish family, possess a strong, hollow, bony leading ray on their dorsal and pectoral fins, through which a stinging protein can be delivered if the fish is irritated.
