Certain decorations in Fish World will give out a decoration or fish as a prize. These are called Functional Decorations and include:
With the exception of the Betta Breeders, functional decorations require help from friends to trigger their timers.
The Starter Breeder costs 25 coins.
The Pro Breeder unlocks free after collecting the required number of fish from the Starter Breeder or you can unlock it early for 12 Fishbucks. You must have the Starter Breeder in order to get the Pro Breeder.
The Master Breeder unlocks free after collecting the required number of fish from the Pro Breeder or you can unlock it early for 26 Fishbucks. You must have the Pro Breeder in order to get the Master Breeder.
All three breeders work the same way. They go through five stages of 12 hours each. At the end of each stage, you click the decoration to start the next stage. At the end of the fifth stage you click the decoration to get your fish. The fish is deposited into your inventory.
All three breeders produce random fish of varying colors and fin design. On rare occasion, each breeder will also produce one of three pre-made bettas. You can find the list of the pre-made bettas here.
Pre-made bettas have a specific name. The randomly designed fish do not. So they will be displayed in inventory without a fish picture, having the name, Betta Breeder.
You can rename these fish by taking them out of inventory, clicking them to highlight and then clicking the name of the fish displayed above its picture on the tool bar. They will retain the name you give it.
At each of the five stages you will get a pop up message indicating the various breeding stages. You can wait the 12 hours and cycle through each stage for free or you can speed up the stage by paying 3 FB. So if you wanted to speed up all five stages it will cost you 15 FB (3 FB x 5 stages).
The breeder decorations will keep producing fish, so don’t sell it. As long as you click the decoration, it will cycle through its five stages giving you a fish at the end.
