📋 About This Mod
Conni243 has updated this for LL and BepInEx. For the latest check out Aquarium Breeding (BepInEx).
I was asked on one of my other mods to make fish in aquariums breed. So, here it is. For each pair, another will be born. Rather than having them all breed at the same time, to keep things simple, I just had the fish breed at different times based on their internal ids, Peepers breed at 8 am, Oculus at 9 am, and so on.
2020-02-14 Fish now breed twice a day, like the Alien Containment.
I hope you enjoy.
