Hi! I'm having an issue in my pack where jellyfish are going ridiculously aggro and killing all nearby fish, leaving their drops floating at the top of the water. This is resulting in hundreds of items just existing in the world and causing lag. Would it be possible to add a config to disable this behavior?

I now realize that the jellyfish are not fully implemented, since they don't have spawn eggs. I mindlessly added them to spawn in certain biomes when I was balancing mob spawns, not realizing they weren't supposed to be. Whoops! Also the Cassiopeia jellyfish are not aggressive, just Box and Immortal. Sorry for the invalid report!
