Tristan's First Pet

We bought Tristan some colorful small fish in August 11th, he liked to feed them endlessly, and he liked to scare them by hitting the shoe cabinet where the fish bowl was placed on top :(

I was thinking of taking the photos of the small fish bowl but I was too late ... The fish died one by one each day and they were all gone after more than a week, I felt so sorry for them, we didn't know the cause of their death, we followed the instructions given by the fish shop helper, we did change water regularly and restrict Tristan from feeding them too much.

I think we won't be buying any new pets for him for a while until we know for sure that we can help him to take great care of them.
