Ok, so I've seen increases in crowds when adding the diver to my For Sale tank. And I've seen additional increases when doing Advertising research. So that part I know about.

The questions are this:

1) Do all customers share the same threshold of what they will pay for a given fish?

2) Even though I see different 'looking' customers, are they basically a generic customer type and the graphics that are shown are just randomly selected, or do 'young boy' customers have different likes and desires (we're talking about the fish here) than 'young girl' customers?

3) Is the purchase process the same with each customer or do they have different purchase logic? For example, will some customers will purchase a fish right away (presuming the price is right) whereas others will wait x number of minutes/seconds before buying a fish--even if the price is right, or is it strictly a price-threshold issue?

4) Do the number of fish For Sale (that means fish of 20 or older) impact the decision process of customers or will they do the same thing regardless of whether there is one fish or 5 or 10?

5) Do fish statuses (Sick, Pregnant, Hungry) affect customer purchase thresholds or purchase decisions?

Any answers (or even vague-but-semi-founded theories) would be appreciated. Thank you.

Yikes! If you can figure out the intricate details of the buying habits of these little peeps, you can pass them along to the rest of us!

I'll tell you that sick fish virtually always require a dirt cheap selling price in order to entice a customer to take it off your hands. Customers don't seem to care about hunger and pregnancy.

The more fish there are in the tank, the faster they sell, and at higher prices. It can take a long time to sell those last few fish unless you lower the price (and who wants to do that)!?!

If you do lower prices to speed up sales in a given situation, don't forget to change it back or you'll be permanently reducing profits.

Ok, so one thing I have noticed. If I have any number of fish in a tank that do not seem to be selling (doesn't seem to matter much if it's 2 fish, 3 fish, or even 5, 6 or more), I exit the Sell Fish mode, wait a second or two, then go back in. Within a short amount of time, I can usually sell 1 or 2 of the fish. I can repeat this usually until I am down to my last fish.

That leads me to believe that the 'customers' have certain purchases 'on their mind' and when you go into the sell screen, you get random customers with random desires. But I haven't confirmed that absolutely yet. Just seems that way. Will have to experiment with it further to see.

I have also noticed that the more fish you have in the tank, the more customers appear in your shop when you go into Sell mode.

I suspect adding tank ornaments has something to do with the minimum number that can appear in your shop, and Advertising research has to do with the Maximum number. Will hopefully be able to confirm that soon.
