U buy tropical fish and get a background and then that is how u can do that
no tropical fish need warm water
yes
Tropical fish can typically survive without a filter in their tank for about 2-3 days, but it is not recommended to keep them in such conditions for an extended period of time as it can lead to poor water quality and stress on the fish.
You should have it running for about 2-3 days before putting fish in your tank.
No. Not in the traditional definition of the tropical tank. A tropical tank is a freshwater aquarium. Regal Tangs are saltwater fish and go in a saltwater tank (marine aquarium).
why not
At least 1 week, test your water before you add any fish, you may need to leave it for longer to allow the ammonia level to come down. I had to leave mine almost 3 weeks.
Probably the fish. I would not put a crab in a tank with tropical fish unless they were a LOT bigger than it was, and it was not going to grow any larger.
No goldfish would prefer to have a lower temperature than any type of tropical fish, however some goldfish can withstand higher temperature if they are slowly acclimated to it! But in the long run goldfish would be happy with other goldfish and tropical fish with tropical fish... there is a reason you don't see the goldfish with the tropical fish in a good aquatic store.
Use a tropical fish tank, preferably new. That way you know that it should not leak. Try to avoid using a tank that was used for something other than tropical fish. I prefer glass tanks over acrylic because they are less likely to mark or look dirty and they are easier to keep clean. Most aquarists will tell you to start off with a small tank and as you enjoy it more and more, you can opt a larger tank. When I started into tropical fish and as I bought larger tanks I used the smaller tank for breeding. Tropical fish tanks and supplies are available in most pet stores that sell tropical fish.
if you have a tropical fish or a filtered tank than yes you do need a light
