Greg's First Pet

Greg's teacher used to have a small fish tank in school and he was quite disappointed to find it gone after the school had a mini renovation mid this year. Yesterday evening we walked past an aquarium, and Greg loved watching the little fishes swimming in the tank. He was so excited when I told him that I have decided to get him a little fish tank so that he could rear some fish himself. The shop owner was quite kind to do up Greg's little aquarium and selected a type of fish that's easy to rear. All in all (including the fish food and a net), the shop owner charged me $10. I thought that was quite cheap!

Greg has all sorts of questions about his fishes... e.g.,
Greg: Mummy, why my fish never sleep?
Me: Fishes do sleep. It's just that they do not close their eyes when they are asleep.
Greg: But I never see my fish sleep...
Me: Your fishes maybe sleeping if they are not swimming about but their eyes would still be opened..
Greg: Yesterday I see them swim, now I see them swim... I don't think my fish sleep you know..
Me: Well, maybe they slept at the same time as you last night.. hahaha.

He's also very enthusiastic about feeding his fishes besides admiring them from outside the tank. He fed the fish once in the morning and half an hour later, he came running into my room with the bottle of fish food.
Greg: Mummy, mummy, I think my fish is hungry. Can I feed them?
Me: You just fed them not too long ago..
Greg: But I want to feed them.
Me: Remember the fish auntie said you cannot feed the fish so many times?? Only once a day..
Greg: Why?
Me: The fish will die if you feed them with too much food.
Greg: But the fish don't want to eat if they are not hungry..
Me: Nope Greggie. I said no means no. You are overfeeding your fish.
Greg: Why?
Me: (getting impatient) Your fish will die..
Greg: I want my fish to die..
Me: What? You want your fish to die?Why?
Greg: Mummy, can you get me new fish if my fish die?
Me: Nope. Now go keep the fish food or I am going to get really angry.
Sigh..maybe he's still too young to feel responsible for the fish.. I wonder if it's the right thing for me to get him the fishes now..
