About this Mod

Banner

Blockfish

This mod adds a new creature called the flockfish. The flockfish spawns in both the lukewarm ocean and warm ocean biomes.

Behavior

The flockfish will spawn in groups of 2-6 and will behave like any other fish.

The Amazing Feature

These flockfish are hungry little fellas and will eat an entire cake in one bite! Upon consumption, the flockfish will rapidly expand into a fish-shaped block and sink to the ocean floor.

Other Stuff

Since there seems to be some interest in this mod, I may update in the future.
Feel free to use this in modpacks (what do you have to lose?)

Frequently Asked Questions

Blockfish server crashes on startup – what to do?

Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.20.1). You can switch loaders with one click in the panel.

Is Blockfish compatible with fabric?

Blockfish officially supports fabric for Minecraft 1.20.1. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with Blockfish – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Blockfish consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
