Aquatic Breeding

Adds a way for fish and squid to breed, manual and automatic!  Fish eat Fish Flakes, Squid hunt for live prey!  Breed Tropical Fish of all colors and patterns! Become your own squid rancher!

Fish will search for and eat any dropped Fish Flakes items and enter love mode, allowing them to breed and lay a “Fish Eggs” item.  When that item despawns in water, it will hatch 1-3 fish of the same type.  Tropical Fish will inherit colors and patterns from their parents, allowing for some mutation in the process.  It is now feasible to collect all 3,072 variants of Tropical Fish!

Squids will hunt live prey (Cod, Salmon, Tropical Fish), and consume them whole.  They will have a 75% chance to enter love mode, and when they do, will breed with each other, producing a Squid Eggs item.  This item will hatch when it despawns in water, releasing 1 or 2 squid of the same type as the parents (Squid or Glow Squid).  Squids can be bred manually using buckets of fish.

Axolotls now have a 50% chance to enter love mode automatically after killing a Tropical Fish.

Squids and Glow Squids now drop their tentacles, which can be cooked, eaten, or traded.  Cooked Tentacles, combined with Cooked Squid Eggs, some wheat and an egg, make the Calamari Supreme, a food item which bestows Luck III for 4 minutes.  If Farmer’s Delight is installed, the Calamari Supreme has a unique cooking recipe amd will bestow Nourishment for 4 minutes.

Some villagers will trade for items added by this mod, and the Wandering Trader offers different types of Fish Eggs.  Glow Ink Sacs and Ink Sacs can brew Glowing and Blindness potions respectively using Night Vision as a base.  Squid Eggs are a brewing item for Water Breathing potions (JEI does not show this due to a bug).

Since this mod uses the AbstractFish and Squid classes provided by vanilla, any modded mob that uses these classes should also be compatible with this mod in theory.  I’ve also attempted to add support for Farmer’s Delight, a few of its addons, and the Diet mod using item tags.  If you want the items added by this mod to be compatible with another mod, please let me know!

Note on ports: It’s unlikely I’ll be porting to other versions or loaders, but maybe if I’m asked enough.  Not 1.12 though.

This mod is extremely configurable (over 80 different options!) so if something isn’t to your liking, there’s probably a way to tweak it.  Visit the Wiki if you want specifics on how this mod works, or if you’re having trouble. 

This is the second actual mod I’ve made, and after two and a half weeks of development I’m pretty happy with where it’s at.  As always though, if you have suggestions feel free to throw them in my Discord – primarily if you’re a modpack developer and want something else to be configurable!  I’ve also set up a Crowdin for submitting localizations!
