I have a couple questions:
1. I have been doing a sort of "noah's arc" technique, but I quickly run out of space in my tanks. I am afraid to "sell-off" the last of each fish, but I know that with 500+ fish, I have to keep doing that. Any suggestions on what fish to sell-off and what to keep?
2. Why can I ONLY sell while in the "store" view? Aren't fish for sale always?

I have more questions but will post them later.
