About this Mod

Visit the GitHub page or preferably dm me directly on Discord to report issues, I check the git once every few months

In Beta due to overhauls and experimental features

Adds aquarium fish and the ability to breed them inspired by 8SidedSquare's angling mod.

I am currently only updating versions in the latest update possible

Entities

  • (Mostly) Breedable modded fish with fish food
  • Over 25 aquatic entities (disregarding their precursor life stages)
  • An average of 1.8022 E+16 amount of possible variants per fish
  • Replaces vanilla squid and tropical fish entities with more detailed new ones
  • Includes non-fish aquatic creatures
  • Entities of differing sizes will attack each other unless pacified!

Simulated Nitrogen System

Waste generated by captive fish and others build up over time in their bodies,
use the Nitrogen Detector from copper to keep track of their nitrogen levels. Once their levels reach 1200 they will begin taking damage proportional to the amount they've reached over that threshold. Use plants or filters to buffer their increase, or isolate fish with high levels until they return to normal.

Terrestria compatibility

Entities can spawn in certain Terrestria biomes.
