dialogue: #Person1#: I saw a beautiful fish in the market the other day, it was orange and blue. I'm thinking of buying some next Sunday.
  #Person2#: Where would you keep them?
  #Person1#: In that round bottle over there.
  #Person2#: It's a bit small, isn't it?
  #Person1#: So are the fish.
  #Person2#: I think you should get a tank if you want to keep fish.
  #Person1#: Really?
  #Person2#: 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.
  #Person1#: That might be quite expensive.
  #Person2#: 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.
  #Person1#: Is there anything else that I ought to get?
  #Person2#: Yes, you need to get some underwater plants, for one thing they keep the water clean, also they make the tank look much prettier.
summary: #Person2# tells #Person1# things that should be prepared for keeping fish, including a tank, some rocks, and underwater plants.
