no!
Yes they are marine animals.
No. Goldfish are freshwater fish and tropical starfish are saltwater fish.
A starfish is a salt water animal that lives in every ocean found on the Earth. A starfish has saltwater in place of blood. That is why they need to live in the ocean's.
starfish are penta-morphic ie. they show penta morphism.
Starfish need to be in saltwater in order to survive. They prefer to live in places that are rocky and textured.
A stafish is found in saltwater only.
A starfish can only live on the and for a very short time before they die. Starfish depend on saltwater to keep them alive and dry out and die when out of the water.
I have never heard of a freashwater starfish, nor a saltwater goldfish, and neither will be happy in the other's water, so no, they cannot live together. If you like starfish, you could get a little saltwater tank for one or two.
Since starfish are saltwater creatures you should be able to acquire one form your local petstore. If no local petstore or they do not carry a saltwater section, then there is always thousands of online retailers.
StarfishNo. No known type of starfish can survive in freshwater. But Starfish can live on land or in other water. They can live some in the ocean, some not, and a lot in shallow cold water.
Starfish live in saltwater, on rocks or reefs
Tropical usually refers to Freshwater tropicals; and so the answer is no, because all starfish are saltwater.
