BitFins began with NFT fish and decor on Cardano. Those originals remain part of the direction for the revamped aquarium.

New fish are planned as in-app collectibles, opening the experience to people who have never owned an NFT. Original collectibles and new app items have distinct roles.

The 2026 Sea Paper explains the planned approach to collecting, original collector recognition, eggs, and trading.
