Fish

The air bladder enables 'those fish that have them' to achieve a neutral bouyance, that is they can remain motionless in one place, or they can sink or rise however they please. Fish that don't have bladders 'such as sharks' are committed to either sink or swim they don't have the added agility or added ease that comes with a bladder.
Definition: Air bladder, also known as the swim bladder, is a large, thin-walled sac that may function as a buoyant float, a sound producer and receptor, and a respiratory organ. Located in the dorsal portion of the body cavity, the swim bladder allows the fish to move up and down through the water. When gas is added by diffusion through the blood vessels in the bladder walls, the fish becomes less dense overall, allowing it to rise. When gas is removed the fish becomes more dense, thus allowing the fish to descend in the water. The swim bladder produces sound by vibrating; these sounds are probably used in courtship. The organ also amplifies water-borne sounds and thus is an aid to hearing. In most fish the swim bladder has no connection to the digestive tract, but in some, such as the lungfish, there is a connecting tube leading to the pharynx, indicating that the organ may aid in respiration.

Ocean fish usually eat a variety of organisms, including plankton, small fish, algae, and crustaceans. The specific diet of each fish species can vary depending on their size, habitat, and feeding habits.

The angler fish is a carnivore that eats smaller fish including cod, haddock, and whiting. The angler fish is an ocean bottom-dweller, and prefers sandy gravel bottoms. Angler fish live in all the oceans of the world.

Yes, a 10 gallon tank can be used for sea-monkeys. It provides enough space for them to swim around and grow. Just make sure to follow the instructions provided with the sea-monkey kit for best results.

Sauries or Sairas are fish which live in tropical and temperate waters. These fish often jump while swimming near the surface, skimming the water. The jaws of sauries are beak-like, ranging from long, slender beaks to relatively short ones with lower jaw only slightly elongated. The mouth openings of sauries, however, are relatively small and the jaws are weakly toothed. A row of small finlets behind the dorsal and anal fins is also a feature of sauries. An unusual feature of these fish is that they lack swim bladders. Sauries grow to a maximum length of about 46 cm. They are harvested commercially as a food fish. Sauries first appear in the fossil record in the upper Tertiary. Pacific sauries are consumed often in Japanese and Korean cuisine. The fish is usually grilled.

Fish are typically most active and feed most actively during dawn and dusk. This is known as the crepuscular feeding pattern. However, the feeding behavior of fish can also vary depending on the species, habitat, and environmental conditions.

Shad is a type of fish. Roe is the eggs of a fish.

The coelacanth is a fish which was believed to have been extinct since the Cretaceous period. However, in 1938 a curator of a museum found a coelacanth in a catch of fish of a trawler off the coast of South Africa. Since then, they have been noted to appear in Comoros, Mozambique, Tanzania, Madagascar, and even in Indonesia. The fish is blue with silver markings and grows to over six and a half feet long. Its population is estimated to be at a number of around 500

The fish was discovered (found) by the crew of the trawler 'Nerine", not by the curator, Marjorie Courtenay-Latimer, of the East London Museum - she made sure it was saved for science! Coelacanths are also found in South Africa and Kenya and it is steel blue/grey with white to pale pink spots and blotches in patterns unique to the individual. The population is unknown - the estimate of 500 or less was guesswork following surveys in the Comoro Islands. It is quite clear that, although nowhere abundant, the coelacanth is widely distributes throughout the western Indian Ocean.

You should be aiming for between 8 and 12 hours. about the same time as the sun is up. this helps with the natural environment of the tank, the plants will grow nicely, there wont be loads of algae everywhere, and your fish will behave more naturally.

this can obviously be adjusted to suit when you will be looking at the tank, after all your paying for it :P. I have mine on around 11am-9pm because this is when im most likely to be home!

too light can lead to an algae bloom and make your tank go green, if this happens don't leave your tank on for so long. it might also help to keep natural sun light off of the tank.

Samon have some! they can jump up and down waterfalls and can remember where they were born, and each year (if they dont die before/after they give birth) they go back to were they were born, and give birth to up to 5,000 eggs. On average, only 1/199 will make it to aldult hood! And they die right after birth, and ,mostly so do the males! hope that helped!

One Oscar needs around 20 Gals. Two can survive in about 30 gals. If you wish to rear Oscars you will need at least 5 young fish to avoid deaths from bullying and you will need to house them in at least a 50 Gallon tank.

Male rosy red fish tend to have brighter colors, especially during breeding season, and can develop small white tubercles on their head. Female rosy red fish are usually larger and have more rounded bodies. Additionally, a trained eye can differentiate between the genital papilla of males and females, which is located near the fish's vent.

no more than it hails taxis. Yes, if you look very closly at a rain drop.......they are puppies and kitties. =] Yes, if you look very closly at a rain drop.......they are puppies and kitties. =]

To attach a fish tank background, first clean the back of the tank and let it dry. Then, use clear tape or a background adhesive to secure the background to the back of the tank, making sure to smooth out any air bubbles. Finally, trim any excess material for a clean finish.

The color red becomes invisible in lower water depths. That's why new fishing lines are made red in color.

Fish usually feed during the day, with peak feeding times being early morning and late afternoon. Different species of fish have varying feeding habits and preferences, but in general, they are most active and likely to feed when water temperatures are favorable and light levels are higher.

An angler fish is a Benthic (or bottom dwelling) fish with the distinctive feature of a glowing sphere attached to a section of spine protruding from their nose. They use this sphere to attract aquatic animals towards their mouth, some of which include fish the size of the angler fish itself. Other than other fish, it eats mainly prawns.

As far as I know with freshwater fish and food is that there are are many things a fish will eat.

Fish Flakes: When it comes to fish flakes lots of fish will them such as Goldfish, Tetras, Small Chicleds, Gouramis, Mollies, Platties, Guppies, and sometimes Betta fish will eat them, They are very high in nutrition, I would recomend feeding a community tank of about 20 gallons at least 2 servings a day.

Fish Pellets: I have had a lot of luck with the pellets and fish, sometimes Goldfish and and the live bearing fish wont eat them, but most others will. I dont recomend this for bigger Chicleds, but great for smaller fish. Bettas will seek this as there primary source of food.

Fish Granules: This is for bigger fish such as Oscars or Koi to eat, this is mostly a base for the Oscar Chicleds diet, but it is necessary for them to eat this daily.

Feeder Fish: Chicleds also need this in there diet, about 2 small feeder goldfish, or 4 small feeder guppies or minows per chicled along with its base food. Crabs will also eat this as its only or primary source of food.

Algea Wafers: Bottom feeders such as Plecostomus, Catfish, and Snails will eat this, Crabs will also eat this as well. You only need to put 1-4 per week for them to eat.

Vegetables: Bigger plecostomus need this as the primary source of food in there diet, Cucumber, Letuce, Carrots, and Broccoli are the primary choices to feed them. I also recomend this for the smaller bottom feeders, but with less of it.

One example of a fish that is typically larger than cod is the Atlantic halibut, which can grow to be much bigger in size and weight. Other fish species that are larger than cod include the Greenland halibut and the Atlantic wolffish.

Half of 10 gallons is 5 gallons, there are 4 quarts in a gallon, and 5*4 is 20.

We realize you've effectively squandered hours of your life playing 2048, the game where you slide coordinating with numbered tiles together to amount to 2048. A few of us at Vetstreet have been going after for quite a long time to tackle the riddle. We were going to surrender when we found that there are creature versions of the game. Also, extraordinary creatures we're talking felines, Dogs and Corgis.I Like Cats video also

Plaice, sole, and halibut are all flatfish. They have a distinctive flat body with both eyes on one side. Plaice and sole are typically smaller in size compared to halibut, which can grow to be quite large.

Clown fish enemies include larger fish, sharks, eels, and predatory marine animals that may prey on them. They are also vulnerable to habitat destruction, pollution, and climate change which can disrupt their ecosystems and food sources. Additionally, humans pose a threat through activities like overfishing and collecting them for the aquarium trade.

Payaras eat all fish smaller than them selves but their favourite foodare piranhas which they impale on their dagger like teeth
