What do marbled hatchetfish eat?

What kind of water does a hatchet fish like?

The marbled hatchetfish is common in the aquarium industry. Like most Amazonian fish, the species prefers softer, acidic water. Hatchetfish occupy the top portion of the tank and like many other aquarium species may be shy at feeding times just after they have been introduced.

How does a hatchet fish fly?

The Hatchet Fish are thus able to make long gliding flights using their powerful “wing-like” fins over the water in nature. This “flight” is made easy by the extremely compressed sideways, almost ax-sharp “prow”.

Why are hatchet fish so fast?

These fins are considerably stiffer than those of most tropical fish. These anatomical traits when combined with their highly developed chest muscle makes of hatchet fish, very fast creatures with absolutely superior maneuverability in the water.

Why are fish so fast?

There are obviously many more aspects to fish speed. Studies have examined the role of lift, eddy currents, turbulence, and other forces affecting fish fin performance. But the basics are enough to keep humans from winning the race.

How many hatchetfish can you keep together?

Not sure how many hatchetfish you have, but they are best kept in schools or six or more. Keeping them in a school reduces the chance that predators, or in this case bully fish, will single out one fish to attack. I have a blue paradise fish that is aggressive to my silver hatchetfish and geophagus surinamensis.

Where do hatchet fish come from?

They are striped-fins fish from South and Central America, the common hatchet fish (Carnegiella Strigata) being the most popular member among the aquarium fans. Taking their common name from the extreme convexity of their ventral surface hatchet fish have a flat back, straight and backwards sweeping pectoral fins.

Why do fast fish have longer tail lobes?

More tail area gives more thrust, so fast fish have longer lobes on their fins. But it takes more than a fin to be fast. The area where the body meets the tail is called the caudal peduncle.

What makes a fish swim fast?

What Makes Fish Swim Fast. As the fin moves side to side, pressure builds up on the thrusting side of the fin and decreases on the trailing side. The gradient causes water to move sideways across the body. This lateral motion can disrupt the boundary layer, the layer of water right next to the moving body (the fish),…

Why are my fish tanks getting dirty so fast?

First, it is important to note why your fish tanks may be getting dirty so fast. The following are the major reasons why: The three main biological toxins that occur in a fish tank, which helps in the pollution of a fish tank, are ammonia, nitrite, and nitrate.

What are the characteristics of a fast fish?

The fast fish, including the great white shark, billfish, and tuna, have several elements in common. They achieve the most thrust with least drag using a thin, tapering caudal fin shaped like a crescent moon, called a lunate tail (great-white tails are lunate, but thicker for more short-range power).

How many fish can you keep together in a tank?

These two will need a tank of their own or they will hurt the other fish or stress them to the point of illness. In a tank of that size, you can probably keep three or four.

How does a fish move its tail?

A fish swims by moving its tail (caudal fin) side to side. While each motion provides thrust and lift, it also creates drag when the fin is angled to the side of the body as a stroke is completed. It takes more than a fin to be fast.

Why do some fish have longer tail lobes?

More tail area gives more thrust, so fast fish have longer lobes on their fins. But it takes more than a fin to be fast. The area where the body meets the tail is called the caudal peduncle. The caudal peduncle also moves side to side as a fish moves its fins.

Why do great white fish have long tails?

They achieve the most thrust with least drag using a thin, tapering caudal fin shaped like a crescent moon, called a lunate tail (great-white tails are lunate, but thicker for more short-range power). More tail area gives more thrust, so fast fish have longer lobes on their fins.

Can a fish tank be too large or too small?

The fish tank shouldn’t be too large or too small. When the tank size is small, it will stress the fish and gets dirty quickly. In contrast, a large fish tank makes fish uncomfortable and will take more time to clean. The most important equipment that collects the waste and debris in a tank is a filter, so ensure that it is high-quality.

What is fish tank pollution and how to prevent it?

The main elements that result in fish tank pollution are ammonia, nitrate, and nitrite. To deal with these harmful elements, you should try your best to remove them from your tank. An incomplete nitrogen cycle results in the degradation of ammonia to nitrites and nitrates. In the end, they become foods for plants and make the fish tank dirty.

Is it bad to clean your fish tank?

Only fish enthusiasts can understand how it feels when they look at a dirty fish tank. It becomes more frustrating when you have cleaned it a week before, and it gets dirty again in no time. It’s always good to have a fish swimming tank around, but fish tank cleaning can easily turn your excitement into a chore.

How to protect your fish tank from getting dirty fast?

These algae grow on the plants and glass of the fish tank. So, if you want to protect your fish tank from getting dirty fast, keep the sunlight exposure to a minimum. Your affection and love can cause more damage than good.

What is the locomotion of fish?

The locomotion in fishes is because of their fins, body muscles and tail. The body of the fish is adapted for swimming in water. They have a streamlined, spindle-shaped body which is covered with scales. This body structure offers the least resistance to the flow of water and makes them swim easier.

Why do fish have a curved tail?

This shape allows them to easily move in water. When a fish swims in water, the muscles that cover its skeleton cause the front part of the body to curve towards one side. On the other hand, the tail (having fins) curves towards the opposite side.

How do fish move through water?

Fish with streamlined bodies and a stiff, crescent-shaped caudal fin or tail, tend to move rapidly through the water by swishing their tail from side to side. This action propels the fish much like sculling (rowing a boat with an oar) propels a boat. The caudal fin or tail is not the only fin a fish uses to swim.

How does a fish flex its body?

There are exceptions, but this is normally achieved by the fish contracting muscles on either side of its body in order to generate waves of flexion that travel the length of the body from nose to tail, generally getting larger as they go along.

What is the shape of the tail fin on a fish?

One of the most important fins on a fish is the tail fin, which is called the caudal fin. Caudal fins – or fish tails – can be many different shapes. The main shapes are rounded, square, forked and lunate. Here are four main caudal fin (fish tail) shapes: Rounded tail: Sometimes this is called a paddle tail.

What is the importance of tail in finfish?

The importance of tail or also known as caudal fin particularly in finfish is very much true based on the previous answers. Most fish require caudal fin as the locomotor to generate thrust for propulsion function, while other fins including pectoral and pelvic control the orientation of the fish in the water.

What does the tail of a fish consist of?

The tail of most fish consists of the fleshy part, called the caudal peduncle, and caudal fin which is the thin part supported by fin rays.
