As a decoration, maybe. As a living entity--NOPE.
I only know of Marine Star fish.
Some are and some aren't.
star fish
yes it can. it will die if you want to put it. it will harden and die
No cos gold fish are cold water fish and star fish are sea water
Yes, If another fish was to eat the star fish whilst underwater then the star fish would die.
some star fish live in salt water
Star fish can survive about 5 days out of water. Then they will die from Dehydration.
A sea star would die if placed in freshwater because the water which is more concentrated outside of the cell, goes through osmosis to try to reach equilibrium this would cause much water to enter the cell and upset the balance of the sea star.
they breath in water and the oxygen from the water they take
it stays in water and live
You can put a star fish in your garden if you want it to burn up and die, starfish need water!
