In captivity the most common problem is ignorance of what a Marine fish needs on the part of the owner.
A water dweller is a living organism that resides in an aquatic environment such as oceans, rivers, lakes, or ponds. These include fish, marine mammals, amphibians, and various invertebrates that have adapted to living in water.
No! marine fish are salt water fish and tropicals are fresh water fish, this cannot be changed.
marine fish lay eggs in fresh water river
Fish are a part of the marine biome. There are two forms of marine biomes: fresh water biomes and salt water biomes.
Here are some animals that live in the marine biome... Eel,sea turtle, tropical fish and rock fish. there is indangered animals like whales.......
Marine fish live in the sea but cold water fish live in cold seas like in the seas of Greenland.
NO do not put tropical and marine fish together because marine fish have salt water that has to have specific things in it other Wise they will die .but tropical fish just have to have warm water with a heater .you cant mix these together because of the water and ALL your fish will DIE.
the marine fish would pretty much suffocate and die. so putting marine fish in fresh water is not a good idea.
A fish living freshwater would be hyperosmotic to its surroundings. This means that it is surrounded by water that is less salty than its blood. Therefore, the main challenge for freshwater fish is to retain enough salt from fresh water for normal bodily functions, resulting in very dilute urine, since they have to get rid of more water relative to salt. A marine fish (salt water fish) has the opposite problem. It is hypoosmotic to its environment, meaning that it lives in water that is saltier than its blood. Therefore, the main challenge for marine fish is to expel enough salt from saltwater to enable it to use the water it takes in for normal bodily functions, resulting in concentrated urine, since they have to get rid of more salt relative to water.
There are both marine (salt water) and fresh water fish in the tropics.
A liquid environment [ saltwater or freshwater ].
These spectacular fish (Pseudanthias species) are tropical marine (salt water) fish.
