In the afternoon, he brought back his aquarium from class complete with fish!
By about 6PM, he told me that all the fishes had died.
On Saturday afternoon, we went to the pet shop again as his friend told him that he has to buy the fish in order to pay back!
So, I bought just a fish of his choice and some water plant. The tank is too small to keep anything more than one fish! I hope that it survives this time.
