This Addon adds 40+ ultra-realistic animated fish from Sharks to Rays to different kinds of Fish! This is a project where the oceans, rivers and swamps come alive! Animals in great detail! Welcome to the Better Seas Fish Public Beta!

There is plenty of life in the oceans in this addon! Most fish spawn natural, but some fish are still experimental! You could find all fishy's in your creative inventory too (Please don't mind the unfinished parts, lol)! The fish are super detailed and have very smooth animations! Most fish have super realistic behaviors as well! All fish interact with each other just like a real ocean ecosystem! Let's watch a documentary!

Delete the older version, before installing the new one! Versions don't stack!

Disclaimer

This is an unfinished experimental addon build, but I chose to publish it early because we have some development difficulties! The content in this addon was much requested! So, we decided to finally share the addon! Please don't mind the unfinished parts! We might not be able to complete this addon! But I, personally, want to make people happy! I really hope people will enjoy this addon, although it's experimental! I hope you understand making decisions could be really difficult!
