DragN’s 'Just Bettas'
This is an official port of my original Bettas & Aquatics that simply adds the Betta Fish, Tanks, and Betta Swamp biome without the other fish. This is not compatible with the original Bettas & Aquatics and shouldn't be installed alongside it.
DragN’s Bettas is a small mod that adds cute, colorful betta fish to your game. You can make a custom-sized tank and add decorations to keep your little aquatic friend happy.
Each betta’s pattern/ body type and color is randomly generated! Find a Betta Biome and look for your favorite variations of beautiful betta fish. There’s over 3400 different possibilities!
Upon bucketing a betta, you’ll receive a Betta Guide to help you out when creating your first tank setup. You may also find other fish and aquatics in the wild to add to your aquarium!
Betta fish have genders, color rarity, and breeding.
Female bettas are generally slimmer, have smaller fins, and are often duller in color than males. Only male bettas will fight one another. They can be bred with Spider Eyes.
Their colors, markings, and body types are genetic!
Requires Geckolib & Terrablender
