Hassan has a very interesting hobby. He collects tropical fish! His bedroom has a gigantic aquarium all around the wall. He has been collecting fish since he was four. His first fish was an Angel fish. The only problem is that they can eat smaller fish. Hassan has visited a lot of different countries like Australia to dive in the beautiful weather there. He has always loved the ocean. Now, he’s fourteen. He has had his big aquarium for three years, since he was eleven.
Last year when Hassan was in Caribbean for his holiday, he saw sharks when he was diving. He wants to have an aquarium where he can keep one or two small sharks, but it’s quite difficult in England. He works as a volunteer at the aquarium of his local zoo. There he can feed the big fish. He hasn’t fed the sharks yet, because he is too young.
