A few weeks ago my dearest friend Miguel died. He was my first betta fish and I had him for around a year and a half.
All of a sudden one day he couldn't move one side of his body anymore and was gasping for air. I put him in a smaller tank because I though he could recover there. He died a few hours later.
Now I have a new friend, Thomas Alva Edison. Edison will never replace Miguel in my heart, however.
