Answer
Hi Kuan;

If your fish is not a betta or a guppy, it is probably a goldfish or another type of fish that is not able to live in a bowl. Any other fish get too big and are too messy so they suffocate and their gills burn in their own wastes. Bowls are just not a safe place for most fish to live. Since your fish is not doing well, you should change water every day. I would suggest also finding out exactly what kind he is and then get the proper size tank with a filter. Here is a web page about goldfish bowls;
