I just bought a new fish today.  I'm so excited.
Woah! That is exciting. Is it a Freshwater fish?
 I have a 100 gallon saltwater tank.  I have a friend who has freshwater fish, but I've only ever had saltwater.
That is cool! Do own any clownfish or cardinalfish?
I do!  I have two clownfish and they are so pretty.  I've never been able to find a cardinalfish.
Amazing! What kind of fish did you buy today?
I got a damselfish.  The species I bought gets along well with other fish, many damselfish don't.  They tend to be territorial and aggressive.
Exciting!! What are the best saltwater fish in your aquarium?
That's a tough choice.  They are all special in their own way.  I think the clownfish are my favorite, just because they are so strikingly beautiful.
Aren't they?! Do you breed clownfish?
