I build Aquariums for a living do you know much about them ?
1_Wizard
Oh how amazing! They must be very difficult to construct.  Yes, actually I do know some about aquaria, such as the first aquarium was built in 1853!

Wow, I wonder how they kept the fish in such great health those days, I'm sure it was a lot of hard work !
1_Wizard
Oh for sure! Do you have a small aquarium at home yourself? 
0_Apprentice
Yes I only keep Tropical fish in it. They are MUCH Prettier then fresh water fish, I want to have some Sharks in mine. 
1_Wizard
How cool would that be?! Sharks intrigue me. I wonder if they have any sharks stocked in any nearby public aquariums.  I have a public aquarium near me in Boston, MA.

That would be fun to see if they did. I would be afraid the Shark would get to big and try to eat me! 
1_Wizard
That would be terrifying! It's my understanding that if any of the animals in an aquarium grow too large or too many of them reside in the tank, there will not be sufficient oxygen in the water for all of the animals. So, I'm sure the size and amount of fish isn't too overwhelming.
