Fish and Bizz
Fish and Bizz adds aquarium fish, aquatic creatures and fishkeeping to the world, and the fish breed when players feed them.
What it does
Fish and Bizz introduces more than 25 aquatic entities, including fish and non-fish creatures, and replaces the vanilla squid and tropical fish with new, more detailed models. Breeding is the core loop: players keep fish alive, feed them fish food and try to balance the tank, and each fish can take on a very large number of possible variants.
Some creatures differ in size, and larger ones will attack others unless they are pacified. Aquarium fish can breed, an ability inspired by the angling mod by 8SidedSquare. Because the mod is still in beta, its experimental features are being overhauled, and the author updates it only for the latest game version.
Fish and Bizz requires Fabric API and Geckolib, and runs on Fabric for 1.19.3 – 1.20.1. Both sides need it, and it is released under the MIT License and is open source, with public links to the source code and issue tracker.
Key features
Aquarium fish breeding
Aquarium fish reproduce with fish food, so a player can keep a small population instead of collecting each species once.
Replaced squid and tropical fish
New entities take the place of the vanilla squid and tropical fish, with more detailed appearances.
Varied aquatic creatures
More than 25 aquatic entities are added, among them non-fish creatures, each with many possible appearances.
Size-based aggression
Creatures of different sizes attack one another unless they have been pacified, which shapes how a tank develops.

How it compares
Angling is open source under the CC0 1.0 Universal license, runs on Fabric for 1.19.2 and is client and server. Additional Fishing is open source under the GNU General Public License v3.0 only, runs on Fabric for 1.20 – 1.20.1 and is also client and server. Oceanic is not open source, is available for Fabric, Forge and Quilt for 1.19.4 – 1.20.1, and is server required with client optional, so it differs in both loaders and environment from Fish and Bizz.
