Betas are very aggressive and will attempt to kill the goldfish. Also goldfish are a cold water fish that produce a lot of waste which could be harmful to the Betta.
Goldfish are meant to live in cold water, not the warm water in a tropical aquarium. This is a huge reason why goldfish and tropicals shouldn't be in the same tank.
they do well. not too cold though!
no
cold is better cuz when your in the ocean is the water hot or cold cold
you put it somewhere where there is no sunlight or light because goldfish die in the heat so use cold water and put it somewhere cold but not that cold
its the respiration rate of the goldfish.

i think most fish, if not all, are cold blooded
