Reef fish are fish that live in the open ocean. They have no natural predators, so they have to find their own way to survive. Aquarium fish, on the other hand, are kept in tanks that are designed to mimic the natural environment in which they live. These tanks are filled with live plants, fish food, and other items that the fish need to live a long and healthy life.
Do fish live in saltwater lakes?
Salmon, eels, red drum, striped bass, and flounder are some of the fish that can live or die in a wide range of salinity. Salmon are among the most abundant fish in the world.
Eels are the largest of the freshwater fish and can grow up to 2.5 meters (8 feet) in length. Red drum can reach a length of more than 3 meters. Flounders are small, fast-moving fish that can be found throughout the ocean.
What fish live in saltwater rivers?
Bluefish, cod, flounder, striped bass, sea trout, tarpon, tuna, halibut, rockfish, sea perch, and swordfish are some of the popular saltwater fish. Bluefish are the most popular freshwater fish in the United States. They can be found from the Gulf of Mexico to the Atlantic Ocean.
Bluefish can grow up to 3 feet in length and can weigh as much as 1,000 pounds. The most common species of blue fish is the bluegill, which is also known as the king gill or king mackerel.
Do all fish live in salt water?
Some fish species can live in both freshwater and saltwater. These fish are called euryhaline fish. Depending on how much salt they can tolerate, most fish species can only survive in one or the other. Saltwater fish can be found in freshwater lakes, rivers, streams, and oceans.
They are found throughout the world, but are most common in the tropical and subtropical regions of the globe. In the United States, freshwater fish are mostly found along the Atlantic and Pacific coasts, as well as the Great Lakes and the Gulf of Mexico. Freshwater fishes are also found as far north as Alaska and south to Mexico and Central America.
How do saltwater fish live?
Because salt is an agent that attracts and draws out water, the surrounding salt water draws water from inside the fish so they must constantly drink water to replace the salt they are losing through their gills. In the wild, freshwater fish do not have to worry about this problem. They are able to regulate the amount of water they take in and out of the body through a process known as gill filtration.
This allows them to maintain a constant level of salinity in the water around them. In the aquarium, however, this process is not as efficient as it is in nature. As a result, fish that are kept in saltwater aquariums have a much greater risk of developing a condition called salmonellosis, which is a bacterial infection that can lead to serious illness and even death in some cases.
Can saltwater fish live in freshwater?
Saltwater fish can’t survive in freshwater because of their high concentration of salt solution. Their cells would accumulate so much water that they would die if the water flowed into their body.
In the case of freshwater fish, the salt concentration in the water is too low for them to survive, so they die from dehydration. The same is true for saltwater crocodiles, which have a high concentration of dissolved salt in their blood.
They die of hypothermia (low body temperature) when they are exposed to high levels of salinity.
Where does fish live?
Fish can live in almost any place that has water. Three quarters of the earth’s surface is covered in water and they have plenty of choices. The world’s seas and oceans have fish in them. They eat a wide variety of plants and animals including insects, crustaceans, fish, reptiles, amphibians, birds, mammals, and birds of prey.
Most fish eat other fish and other animals, but some fish do not eat at all. For example, some species of fish (such as swordfish) eat only plankton, while others, such as tuna, eat mostly fish. In general, the more fish a fish eats the better it is at surviving in its environment.
