W : I saw a beautiful fish in the market the other day. It was orange and blue. I' m thinking of buying some next Sunday.
M:Where would you keep them?
W:ln that round bottle over there.
M: It's a bit small, isn't it?
W:So are the fish.
M:I think you really should get a tank if you want to keep fish.
W : Really?
M : Yes. You should never keep fish in a small round bottle. They don' t get enough air. I suggest we go shopping together and look for a nice tank.
W:That might be quite expensive.
M: Check the prices before you buy one. And you ought to put a few large rocks in the tank. Fish love swimming around the rocks and through holes in them.
W:Is there anything else that I ought to get?
M:Yes, you need to get some underwater plants. For one thing they keep the water clean. Also they make the tank look much prettier.
