Tank

**Tanks** are the areas where all Fish and Plants in FishCo are stored. Tanks have a limited amount of space which must be managed, and other stats to keep track of to keep Fish healthy.

## Tank Status

All gameplay tanks have a Tank Status menu that can be viewed for several pieces of information:

### Fish Capacity

Fish Capacity measures the number of fish that can be placed into a tank. All Fish in the game have an associated size, and so larger fish, such as the Zebra Cichlid, will take up more space than a smaller fish such as the Cardinal Tetra, and thus fewer can be placed into a single tank at one time.

### Plant Capacity

Plant Capacity measures the number of plants that can be placed into a tank. Much like Fish Capacity, how many plants can be placed into a tank depends on the size of those plants in addition to the capacity of the tank.

### Water Quality

This feature is exclusive to Action Mode and Relax Mode only.

Every tank has a water quality level. The water quality level will stay static if the tank is empty, but if there are fish or algae in the tank, the water quality level will slowly decrease. This is true even if the fish are all dead.

When the water gets too dirty, fish will begin to get sick. They will need to be treated with Medicine to prevent them from dying.

The only way to increase water quality is to clean the tank, which takes time and disables any other activities from being performed while the cleaning is ongoing. Additionally, no fish can be sold from a tank that is being cleaned. Cleaning is temporarily disabled during Breeding.

Though there is no other way to raise the water quality, it is possible to slow its constant entropy. Certain plants help keep the tank clean, as do filters.

### Filter

Filters will help keep the tank clean for longer. Letting the player spend less time on cleaning and putting fish at less risk of disease.

List of Filters:

* None - Default
* Undergravel - $25
* Bio Wheel - $50
* Canister - $75

### Light

Every Plant species has a light level requirement. The light will need to be updated to accommodate certain plants. It has no effect on fish, but does have a visual effect.

List of Lights:

* 15W - Default
* 30W - $50
* 50W - $50

### Algae Sponge

The Tank Status menu also allows the player to select the sponge to clean Algae.

## Tank Types

### Sale Tank

Sale Tanks store fish to be sold.

In these tanks, there is a "Market" tab where the player is able to sell Fish. There is also a "List Fish" option upon selecting any fish, that allows the player to put that specific fish up for sale.

### Breeding Tank

Breeding Tanks are where fish are bred.

Breeding tanks can only hold one type of fish at a time. The market tab is replaced by a "Breeding" tab, which allows the player to spawn fish eggs of that type for free if there is an adult male, adult female, and enough space for at least one more fish of that type in the tank. Fish cannot be sold here.

### Sandbox Tank

These tanks are only available in Sandbox mode. Fish here cannot be bred or sold. Decor can only be purchased in these tanks, replacing the Medicine tab in the menu as fish cannot get sick in the Sandbox mode. Fish cannot be transferred between different sandbox tanks.

## List of Tanks

### Rock Sale Tank

This is the first tank unlocked in the game. It has turquoise blue gravel with patches of moss, and mossy rocks as decor. It is renamed to "Blue Tank" in the Sandbox Mode, and all of the rocks are removed.

* Fish Capacity - 9
* Plant Capacity - 3
* Decor Capacity - 3

### Ruins Sale Tank

This tank has orange gravel and model Hellenic ruins. In the Sandbox Mode, the ruins are removed and it is called the "Orange Tank."

* Fish Capacity - 11
* Plant Capacity - 4
* Decor Capacity - 3

### Mermaid Breeding Tank

As the name suggests, this tank has a mermaid as its only form of decoration. Instead of gravel, the bottom is padded with red sand. In Sandbox Mode, the mermaid is removed and it's called the "Red Tank."

This tank is unlocked on Level 8, and is the first breeding tank available in the game.

* Fish Capacity - 10
* Plant Capacity - 3
* Decor Capacity - 3

### Clam Breeding Tank

This tank has green gravel and its only decor is a model clam.

* Fish Capacity - 15
* Plant Capacity - 5
* Decor Capacity - 3

### Treasure Sale Tank

A tank with purple sand and a treasure chest for decor. The background of this tank, instead of consisting of a fish store interior like the rest, is of a street viewed out of a window, presumably one of the front windows of the store.

* Fish Capacity - 15
* Plant Capacity - 5

## Other Tanks

### Main Menu Tank

This is an unplayable tank that cannot be interacted with, but can be seen on the main menu of the game. Instead of the sale or breeding tank signs, it has a sign with the logo of the game on it. It has the following inhabitants:

* Harlequin Rasbora
* Betta
* Marble Hatchet
* Zebra Goldfish
* Clown Loach

* Repens
* Melon Sword

There are also some rocks and a mermaid serving as decoration. It seems this tank operates on Sandbox mode logic, as the Betta would otherwise kill every fish present aside from the Clown Loach.
