I lost one of my female guppies today. I was so upset, my mom told me it is hard to raise fish but I can not help woundering if I did anything wrong. The only thing I can think of is that I need to do a water change, I have not done one in a week. But I thought that water change is a weekly thing but maybe I need to do it more than once since I have not got my new tank and my tank may have to many fish right now. Now I just hope the rest of them live because if they all die then I do not think that I can manage to try more guppies and will have to look at some other kind of fish.thanks
