Some aquarium salt is good for fish, the recommended amount is 1 tablespoon for every 5 gallons, however some aquatic plants and scaleless fish are very sensitive to salt and it will kill them. Cory Catfish are one of those fish.
yes all puffer fish can survive in fresh water areas
No. Puffer fish can only survive in the ocean.
Fresh water fish survive just as well as fresh water fish. Maybe this question isn't the one that you actually meant to ask?
A Siamese fighting fish/betta? Yes! They cannot survive in salt water.
hi how r u today
Saltwater fish require salt water, and fresh water fish need fresh water, you can't mix them, or the fish will die. You need to look at each individual fishes needs as to what temp they need their water to be. There are some saltwater fish that can survive in fresh water, but it is not healthy for them.
If it is a fresh water fish than it isn't really meant for salt water. Do some research on the breed of the fish though because some can survive in salt water.
It is about osmoregulation. Salt water fish has some level of salt in its cells, which is low in concentration than marine water and more than the freshwater. If you put a saltwater fish in fresh water, excess amount of water will enter the cells of the fish and the cells rupture. This is why salt water fish cannot survive in freshwater.
the marine fish would pretty much suffocate and die. so putting marine fish in fresh water is not a good idea.
if u get to drink water, fresh water not from the ocean, then yes
No... but if you put it in Fresh water, then technically it would be. Unfortunatly, it would not survive. :(
Damsel fish are OK in a Marine (sea water) environment. They will not survive in fresh water.
