You have to buy all of your fish....
Happy Aquarium last forever. If you do want to get rid of your fish, just sell them. The best fish to sell are the adult fish.

10000 is not hard, you must click your neighbor chest daily then select the most profitable fish, i manage to get up to 30000 now. :) if you need the full list go here http://www.yayeasy.com/happy_aquarium/happy-aquarium-fish-details-and-profit/
no, you are only able to mate same types of fish or turtle
You cant
yes
Well, to buy a pet you just click on the store icon in the lower left-hand corner and the fish are the first thing that come up and you pay coins or pearls or facebook credits to buy them (depending on what fish you are buying). But if you mean like how do you adopt a turtle, penguin, or squid, well then you have to wait for a friend who has Happy Aquarium to find one (they come up randomly) and then a notice should come up on your facebook homepage saying that this particular animal needs a home and then you click on 'Adopt baby squid/penguin/sea turtle' (whichever one it is) and then you will be able to adopt it. Unfortunately, if you find one of those animals yourself you won't be able to adopt it. only friends can.
