If your fish aren't breeding, they might be hungry. Try standing next to the fish tank and see if you can see a small fish icon on top of it. If you see it, they're hungry. Fish will only breed when they've had X days without starving.

If that's the problem, you need to make a lot of dough (not cash, fish food). Try checking how much food they need before the "hunger" icon disappears, and try to calculate how much food they'll need until you refill the tank the next time.
