The Saltwater Tank, also referred to as the Abyss Tank or the Abyss World, is the first tank that is available to the player upon starting up the app. It features an inactive underwater volcano, known as "Lonely Corallite" by the game, who grows with each upgrade added. These upgrades can vary from tapping bonuses, to Normal and Fusion Fish, to a variety of Coral all found in the Main Tank Tab. Additionally, there are 5 Material Farms that the player can create, each of which provide vital materials to spend on Decorations, fusion fish, and more!
All Saltwater (Abyss) Fish
Thanks to SirTapTap for all the requirements for these fish!
Below is a complete list of all the fish found in the Normal section of the Manage Fish menu. They are usually unlocked in the order they are displayed, but some of them are unlocked much later. Hidden fish are highlighted in a brighter purple color.
The coral available to the player serves many purposes. Its first, and possibly most blatant, is its ability to unlock new fish. Secondly, every new type of coral unlocked boosts the player's Max Fish Count by 5, and also provides some extra Vitality, albeit not very much.
