The Tank Room - Where Miracles Worked On Fishes
The Tank Room is one of the 3 rooms you can find in your Cottage. It contains tanks or aquariums where you can place your captured fishes, feed them, and grow them up into a bigger and stronger personality when they are released back into the nature in the end. The Tank Room has 3 kinds of tanks, which is the Seawater Tank, the Freshwater Tank, and the Running Water Tank each with the same capacity of maximum 5 fishes. Each tanks has their own background and their own types of fish that can be put inside them.

Tank Menu
By choosing a tank, you will open up a list of action that can be done. From top to bottom would be Transfer Fish into Tank, Check Condition of Fish, Look in Tank, and Release Fish. As their names implies, here you can put fishes into the tank, check a fish's condition, health, and current length, look inside the tank to feed fish and grow them, and lastly to release fishes kept inside the tank or the Keepbox.

Weaknesses
Though very logical, it is unfortunate to not being able to keep fishes that comes from Trolling and GT Fishing. Why? Because the fishes that comes from this two fishing spots needed a large space where they could swim endlessly like they did before they were caught. Therefore, the only choice is to release back the fish into it's habitat.

Feeding, Growing, and Tips for Growing Fishes
Feeding is essential to make your fish grow into a bigger size than the size when they were caught. Fishes need to be fed at least twice a month or what's better every week of the game. When feeding occurs, fishes will regain health and will their body size will increase. The increase of the fishes' body size is called Growing.

However, Growing a fish is harder than imagined as fishermens cannot just feed their fishes to make them grow, as there is a way to make fish grow. How does this actually work? Each knock on the tank puts stress on the fishes inside it and their health will decrease. The above conditions are the optimal number of knocking should be done on fishes based on their health. The above number of knocking is designed to reduce a fish's health into tired. A tired fish will eat more to regain it's lost health which eventually will increase it's health back to healthy and their body length will also increase by roughly 0.02 - 0.05 feet.
 * 1) First, put in the fishes you just have caught from the fishing spot you were just before into the tank.
 * 2) Next, check the condition of the fishes and remember each fish's health.
 * 3) Then, look inside the tank and knock with a light knock or a heavy knock based on these conditions:
 * Don't knock: When the fish's health is Tired.
 * Knock 5 to 10 times: When the fish's health is Good.
 * Knock up to 15 times: When the fish's health is Healthy.

Through experiments, it is found out that a larger number of knocking than those stated above will result in the fish health won't increase to a healthy status no matter how much feeding is done. This can only be cured by waiting for the next week which means for the next chance to feed them to increase back their health.

When facing with multiple health conditions at once, do not knock, instead feed the fish to increase their health. It is best to knock when all the fishes' condition in the tank are the same. This is yet a very complex and difficult way to grow fish, but that's how growing goes in this game. Sadly, there is a limit to how long a fish can grow. Rumor has it that if a fish that is kept in the tank grows up into it's maximum size and is released into the wild, the size of the fishes of the same species that can be caught will also increase based on the last fish's length. And if a fish of the same species that is caught is longer than the previous record, and if the fish was kept and fed in the tank, the maximum length for that species of fish will increase, which allows for infinite length for each fish. However, this has not yet been confirmed to be true.

Conclusion
Feeding and Growing a fish is hard and takes a lot of patience and hardwork. However, watching your fish grow with the maybe limitless potential your fish has in growing is more than enough to compensate for all those hard work.
