It depends on how often you clean the tank. you dont need a sucker fish if you clean your tank alot. If you dont clean your tank that often then get one. you should talk to your local pet store for more information.
They usually do not need to be cleaned unless you are using a cylinder for nitrox.
At least once a week. Twice is usually good.
Your fish tank doesn't need to be cleaned. It's always clean.
Once a month.
No but you will need a filter and a air pump to circulate and oxygenate the tank. Gravel is optional but I prefer not to use it because it traps the feces and access food. You will also need a syphon, and a scrubber to clean the tank. You should clean the tank about once every few weeks or when it gets cloudy. When you clean your tank you will probably notice that the water is still a little cloudy but it's ok because you won't be able to get the tank completely clean.
Yes. You must clean everything you put in your fish tank. Also for plants, you need to clean it and wait 2 days to put it in the fishes tank.
