However, I have to report the passing of 3 of them to causes unknown. Maybe the changing of their water disturbed their tiny little bodies. I heard that temperature changes can throw them off. Perhaps I fed them too much. The third of our fish to depart this life was my personal favourite whom I had named Xavier. It was sad to see his tummy ballooning until I woke up yesterday morning to find him lying prostrate on the stony floor with no signs of life. I hope I didn't overfeed him, although none of the others have had the same problem.
Anyway, we are down to 5 now. Maybe there were too many fish for such a small aquarium. Well, so far they seem happy now, the remaining five. Hopefully I won't have to report any more deaths for quite a while!
