Goldfish and betta cannot mix raise together, specific reason is as follows:
1, breed is different: Goldfish is coldwater fish, betta is tropical fish, the environment that both wild lives is different, do not suit to live together so.
2. Water temperature and water quality are different: the water temperature that goldfish likes is 22-25 degrees, and the temperature that betta likes is 27 degrees. The two temperatures do not match. If the temperature is too high, it will cause discomfort to goldfish. If the temperature is too low, it will lead to loss of appetite. Therefore, it is not easy to control the temperature when they are mixed together.
3, disposition is different: The disposition of goldfish is more gentle, betta is more ferocious, territorial consciousness is stronger. So if they are mixed together, the goldfish are likely to be injured or even killed by the fighting fish.
4, food is different: Although goldfish and betta are omnivorous fish, but betta is partial carnivorous, if they are mixed together, it is likely to cause a single kind of fish food, can not grow healthily.
with what fish goldfish can be mixed with fortune fish, lantern fish, angelfish and so on, because the body shape and living habits are similar, so mixed together is also more convenient to take care of. You can also raise some small and flexible fish, so that goldfish can not eat them, but also exercise.
