Right,

got this game - like it so far!!!
BUT I cannot sell fish!
I wait till their old to breed, drag them to the iso tank ans press "sell fish" - but the shop shows "fish still for sale":0

No matter what I do I can't sell.

I've reduced prices & everything - fish are healthy!

HELP!!!!

You need to put them in the selling tank (the tab on the far right, marked $). Then tap Sell. You might want to fix the prices before you do that, so you will get more money!

DOH!!!!

Thanks, Iso or selling tank - all fishy to me!!!

How do I set the price of fish for sale?

It's easy! Put the fish you want to set the price for into the isolation tank and tap the Species button. You'll be taken to a screen that shows you information about the fish and its parents. You can set the selling price for that species from there, and on Palm OS devices you can also change the name of that species of fish.
