new pet

I don't know if it is a gift or a mess. From my "big sis" in swimming I got a pet fish for my gift. He is cute and small. He is blue and black and well a beta. Since he is a beta well they are well known to be a mess and well smell. He seems like a nice fish but after two days he is already starting to smell. I am so busy all the time I don't have time to clean a fish bowl every few days. Also, beta fish have a tendancy to live kind of long. My neighbors beta fish lived for six years. I think its so cute that she got me a fish, yet its not in my best interest to even have the simplest pet. I can't get rid of it, because it is a swimming tradition to keep and take care of your fish for as long as it lives. Also, when I leave for weekends for meets for some times three days, am I going to have to get some one to take care of this fish. The nicest ideas can sometimes turn into bad outcomes. I am looking at my fish bowl right now and see that it is cloudy and dirty. I just sigh and say ugh, for I know this is the future with my pet fish.
