seconds my dude
A saltwater fish tank can be half freshwater and all of the saltwater fish will live but not for very long.
Freshwater fish would not survive the salinity of the sea for very long.
It stays lodged in the fish's mouth. In saltwater the hook will eventually corrode away; not sure how long tha takes in freshwater.
Yes, I had a guppy live in my saltwater tank for a year. They are considered a brackish fish.... so they can adapt to a higher salinity level
Salmon is a migratory fish that is known for traveling long distances between freshwater and saltwater habitats during different stages of its life cycle.
The various species of fish found in oceans, lakes, rivers and streams have evolved over millions of years and have adapted to their preferred environments over long periods of time. Fish are categorized according to their salinity tolerance. Fish that can tolerate only very narrow ranges of salinity (such freshwater fish as goldfish and such saltwater fish as tuna) are known as stenohaline species. These fish die in waters having a salinity that differs from that in their natural environments. The only fish I know of that lives in both is Pacific salmon. Salmon are born and they reproduce in the safety of freshwater but spend the rest of their lives in the oceans. This type of fish (fresh and salt water) are called anadromous.
Salmon can live in freshwater and saltwater and migrates when it is full grown.
Trout are primarily freshwater fish and are not well adapted to live in salt water. However, some species, like the steelhead trout, can migrate between freshwater and saltwater environments, spending part of their life cycle in the ocean. This ability to tolerate saltwater is an exception rather than the norm for most trout species, which thrive in rivers, lakes, and streams. Generally, true trout cannot survive long-term in saltwater conditions.
Well, that depends on what type of fish they are. Just like fresh water fish cannot survive in salt water, fish which had lived in hot water cannot live in cold water.
Bangus, or milkfish, primarily thrive in brackish water environments, such as coastal areas where freshwater and saltwater mix. They are not well-suited for freshwater ponds, as their physiology is adapted to higher salinity levels. While they may survive for short periods in freshwater, their long-term health and growth would be compromised. For optimal growth, bangus should be raised in brackish or saltwater conditions.
The fish that looks like a snake is called an eel. Eels have a long, snake-like body with no scales and can be found in both saltwater and freshwater environments.
Goldfish will do fine in a fountain, as long as they are fed, and that the area is big enough to swim around and not all fountain! As long as the fountain isn't too powerful the fish will do fine.
