Can lungfish be kept with other fish?

What makes the lungfish so unique?

The lungfish eats by sucking prey into their mouths and crushing it between their jaws, chewing thoroughly before swallowing — a truly unique way for a fish to eat, which further links it with cud and meat chewing terrestrial animals. Another intriguing attribute of the lungfish is that they can hibernate out of water.

How do lungfish survive in dry weather?

At the onset of the dry season when water bodies dry up, this species is able to secrete large quantities of mucous. The mucous hardens to form a cocoon in which the fish stays dormant for several months. Other species of African lungfishes also have this ability to varying extents. The South American Lungfish can only breathe air.

How much oxygen does your fish need to grow?

This is not generally realised but is vital when designing aeration systems for growing on warm water species. Most research indicates that trout consume around 200 – 250 mg O2/kg/hour. I regularly record carp consuming three times as much at 700- 800 mg/kg/hour under optimal growing conditions.

What makes a lanternfish unique?

After all, lanternfish make up one of the largest families of fish in the ocean, so they must be doing something right! Lanternfish are small fish that live most of their lives deep in the ocean, although they swim up at night to eat and avoid predators. Lanternfish are unique because they can make their own light using bioluminescence.

Why is there so much oxygen in my fish tank?

For fish this means an aquarium, and the aquarist is the one who determines many factors in how much oxygen is in the water. i.e. too many fish in too small a tank. This may be caused by physiological problems or disease. Oxygen dissolves in water easier if the water is moving.

Does a fish tank need oxygen and other chemicals?

A sturdy balance should be found that sustains both oxygen and other chemicals. If not, a fish tank might become a deadly environment for all aquatic life. A fish tank’s water needs to have a good balance of oxygen and other chemicals to keep all aquatic life alive. How to calculate the right amount of oxygen for a given size tank?

Where are the photophores located on a lanternfish?

The photophores are located on the fish’s head, underside, and tail. It is believed that these light organs are used to attract other small fish on which the lanternfish feeds. They may also be used to signal other lanternfish during mating. Photo of a lanternfish. photophores are visible as white dots.

Why do lanternfish make their own light?

Lanternfish are small fish that live most of their lives deep in the ocean, although they swim up at night to eat and avoid predators. Lanternfish are unique because they can make their own light using bioluminescence. They probably use this light to help them find food, scare off predators, and communicate with each other.

How many lanternfish are there in the world?

There are around 240 known species of lanternfish in the world’s oceans. They prefer to inhabit depths of up to 4,500 feet, where light is a scarce commodity. These abundant fish make up approximately 65% of all biomass in the deep seas.

How does oxygen affect aquariums?

It also increases the rate at which carbon dioxide (CO 2) is released from the water. The amount of oxygen in your aquarium plays a major role in determining how many fish you can keep in your tank. You need enough oxygen to keep each fish alive!

Why are there bubbles in my fish tank when they breathe?

Because cold water can contain more oxygen than warm water, the oxygen gets trapped due to the extremely fast temperature change. When your fish breaths in the over-oxygenated water, the oxygen leaches out of your fish’s blood stream and forms bubbles in the tissues.

Can fish breathe in water that is too saturated?

And once saturation is achieved, no more oxygen is going to dissolve in the water. Your fish will happily breath in water that is saturated with oxygen – it’s harmless. But the problem comes when water is supersaturated with oxygen. And I must stress that this isn’t common in an aquarium environment. [ 6]

Why do lanternfish flash their tails?

Some lanternfish (myctophids) have very bright light organs near their tail (white caudal organs). These stern chasers produce a blinding flash at the instant that the animal darts away, leaving a confused predator in its wake. Photograph by Steve Haddock.

What is a lanternfish (myctophids)?

Lanternfish (Myctophids) have a large number of light-emitting organs (bioluminescence) and are important prey for southern elephants seals. The lanternfish or myctophids are very abundant midwater fish found throughout the world’s oceans, consisting of approximately 300 species, many of which undergo diurnal vertical migrations.

How did the lantern fish get its name?

They are aptly named after their conspicuous use of bioluminescence. Their sister family, the Neoscopelidae, are much fewer in number but superficially very similar; at least one neoscopelid shares the common name ‘lanternfish’: the large-scaled lantern fish, Neoscopelus macrolepidotus .

How many eggs does a lanternfish lay?

Lanternfish are known as unprotected pelagic spanners. This means that females release their eggs in a column of water as a group where they are externally fertilized by males. Depending on the species, 100 to 2,000 eggs are released through each fish.

What is the pattern of the photophores on a fish?

The photophores emit a weak blue, green, or yellow light, and are known to be arranged in species-specific patterns. In some species, the pattern varies between males and females. This is true for the luminous caudal patches, with the males’ being typically above the tail and the females’ being below the tail.

What type of photophores do fish have?

The fish possess species-specific serial photophores and/or luminous tissue. The mostly ventral primary photophores are well developed and contain lenses, while smaller, less-developed secondary photophores are distributed over the body.

Can lanternfish see in the dark?

Lanternfish create their own light so they can see in the dark. Lanternfish live most of their lives about 3,000 feet beneath the surface of the ocean. They swim up closer to the surface at night to find food and avoid predators, but they’re usually completely in the dark.

Where are lantern fish found?

Lantern Fish Facts- Where are lantern Fish Found? As per the source, Lantern fish (or Mycotrophids, from the Greek μυκτήρ mike, “nose” and oophis, “snakes”) are small Mesoplasmic fish of the large family Mycophyidae. Mycotrophs is one of two families in the order, represented by 246 species in 33 genera Mycotphidae and is found in oceans worldwide.

Is a lanternfish A mycotroph?

Lanternfish are small mesoplasmic fish of large families in the macrophyde. Mycotrophs are one of two families in the order, represented by 246 species in 33 genus Mycotphidae, and are found in oceans worldwide. They have been duly named after the use of bioluminescence.

Can fish breathe oxygen from water?

This may sound crazy since water contains oxygen already, but it’s really not. The hydrogen and the oxygen that make up water are inseparable meaning your fish cannot extract the oxygen to breathe it. Rather, fish obtain their oxygen from the surface of the water where a process is known as a ‘gas exchange’ takes place.

How does salinity affect physiology and behaviour?

Interactive effects of salinity on physiology and behaviour have to be taken into account: tissue permeabilities to water and ions, gill ventilation, perfusion, functional surface area, types of metabolic substrates catabolized, among others ( Swanson, 1998 ).

How does salinity affect the growth rate of fish?

In larger fish, salinity is also a key factor in controlling growth. Do the changes in growth rate, that depend on salinity, result from an action on: (1) standard metabolic rate; (2) food intake; (3) food conversion; and/or (4) hormonal stimulation?

Why does my fish poop have bubbles in it?

When fish leave excrement, some of the waste can coat small air bubbles, causing these bubbles that would normally dissipate to stick together in a foul-smelling foam. While it can happen in freshwater tanks, it is more common in saltwater aquarium systems.
