Better Fishtanks
Better Fishtanks adds a framework for building aquariums, with fish from vanilla Minecraft and from other mods kept in tanks that players decorate and manage.
What it does
Tanks are decorative blocks that hold fish, and the mod adds more glass block variants for building them. Players can populate a tank with vanilla fish and fish added by other mods, and the Dynamic Fishtanks system tracks the aquatic ecosystem inside each one. Fish are kept healthy by feeding, and the mod adds several new food types.
Fish move between places in Fish Bags, which carry a single fish safely from one location to another. Random Fish Bags hold an unknown fish, which can turn out to be any vanilla species. The Aquarist Table works as a central hub for fish-keeping supplies, where players craft and manage what their tanks need. The mod requires MINT Lib, which must be installed alongside it.
The mod is available for Fabric, Forge, NeoForge and Quilt, with builds covering 1.20.1 – 26.2. Only the latest Fabric, Forge, NeoForge and Quilt files shown here target 26.1.2, 1.20.1, 26.2 and 26.1.2. It runs on the client and the server, so both need it, and it is released under All rights reserved and is not open source.
Key features
Dynamic fishtanks
Tanks hold a mix of fish and track the ecosystem they support, so the aquarium changes as the fish live in it.
Feeding system
Fish need feeding to stay healthy, and the mod adds flakes, dried kelp, mini-shrimp and pellets as food.
Pellet mix
Players craft a special pellet mix for their fish, and a container holds each food type separately.
Fish bags
Fish Bags carry fish from one place to another without harm, and Random Fish Bags give a surprise vanilla fish.
