Heck no! I would highly discourage tanking common goldfish and Siamese fighting fish together. I have one of each myself, and they each have their own personalized homes and feeding/water changing schedules. Bettas are called "Siamese fighting fish" for a reason; the males are highly territorial and are fit to kill.
A couple times a week I'll hold a mirror in front of my betta and he shows all his fins, and tries to attack his own mirror image. It is not good to do this for too long, as it will wear them out. Common goldfish are referred to as "feeder fish" because they make great meals for larger carnivorous fish. Though male bettas aren't very large, they are still carnivores.
A Siamese fighting fish/betta? Yes! They cannot survive in salt water.
I think what you are referring to are fish who can survive in an aquarium without harming other fish. Goldfish and guppies are a couple.
a Siamese cat can live any where in the world sometime it lives in the jungle
No.
no
Goldfish cannot live in rivers, they are 100% aquarium fish. They do not have strong enough immune systems to live in the wild and they cannot survive the fall and rise of the temperaure outside year round. Also river water will be to rapid for the fish to swim in.
yes
Yes, goldfish can survive without food for two days.
No you mook
Yes. Goldfish hear vibrations in water with tiny bones in their head. If you tap on fishtanks, the goldfish will be overwhelmed and probably suffer a bad headache! That's why goldfish get scared if you tap fishtanks.Yes! And not just common noises but also noises caused by vibrations of objects. For example, when you thunk against the aquarium (NEVER DO THAT) this generates sound. Or if you thunk or hit the table on which the aquarium is (NEVER DO THINGS LIKE THAT), this also generates sound.
star fish
Only in an aquarium.
