how to keep the fish in aquarium

Everyone must have a hobby, and some hobbies are channeled by spending a lot of budget.
on this occasion I want to discuss how to keep the fish in the aquarium and how to keep the water always fresh.
You can followed my way to keep your fish stiil fresh and healthy

1.) the fisrt way , The water still clean and fresh everyday .
how can do that , just a simple , because every market sell a water cleaner machine but many water pump mechine cannot clean the water , you should used the filter above the water pump, so it will filtering out all the fish debris, and always clean the fish dirt once a week and if you not to able to buy another filter, you simply insert the filter into hot water so that the filter is free of worms and fresh again .
2.) You should feed the fish 3 times a day , and vitamin fish between two till three day times .
but , some fish will die because some fish cannot too much eat for a day .

that's the two ways I can shared to my friends according to what I learned when I was fishing in an aquarium
