# Fish

## How to Obtain Fish:

You can purchase a fish mystery box in the store. Upon opening the mystery box, you have a chance to obtain different types of fish, with the probabilities as follows in the table below:

## Fish Pond Settings

When you acquire fish, you can place them in a fish pond. The fish pond distributes rewards every 10 minutes (shared among all the fish in the pond). The fewer the fish in the pond, the greater the reward for each fish; conversely, the more fish in the pond, the smaller the reward for each fish. There are currently five fish ponds, each with a different amount of tokens allocated as follows:

The different types of fish you place in the pond will also have varying weights in terms of the rewards they can earn. The specific details are as follows:

## How Fish are Upgraded

When you have two fish of the same star level, you can upgrade them and place them in a new fish pond. Each time you level up, there will be a period during which you cannot upgrade further. The specific upgrade cooldown times are as follows:

## Fishing

You can buy a fishing rod to fish, on the condition that each fish pond contains at least 300 fish.

The more fish there are in the fish pond, the higher the probability of successfully catching a fish.
