So I get a little obsessive at times and my mind is going about 100mph right now. The topic: Aquaculture. So if you could look at this little graphic and answer a couple question, I would appreciate it.

1. Would this work?
2. What fundamentals am I missing? (Besides fish.. )
3. How many feeder type goldfish would this support?
4. Is this a decent (and cheap) way to 'test the waters'?

Thanks for looking,

NM
