Some issues with Bull Shark and Sea Lion (1.20.1)

[Vinzound]

I know that in the latest update you can configure the appearance of some mobs, but I would like to make two observations.

• I know that bull sharks can live in freshwater, including rivers, but I think their spawn rate in the river biome is too high, to the point where I only see ink sacs and almost no live squid XD

• This last one is more serious, because in all the tests I've done, I've never found a sea lion naturally in the worlds I create, even when I increase their spawn rate in the settings. Honestly, I don't know if this is a bug or if it has something to do with the fact that I also have Fintastic and Alex's Mobs installed.

To my understanding it's not completely fixable with just the config of this mod.

How Mob spawning works, is that minecraft mobs spawn until it meets the mob cap of each mob category.
So Squid and Sharks both share the mob category of Water creature, and in minecraft water creatures have a cap of 5. So when you're in the river, the game will see if there are any mobs in the water creature category around you. If there aren't then they'll try spawning some, in this case either the shark or the squid.

If the game spawns 4 squids and 1 shark for example, there are 5 water creatures, so the game stops spawning any more.
The problem comes when the shark hunts the squids, squids get killed and there is once again an opening to spawn more water creatures.
Either more squids spawn, but they get killed by the shark again...
Eventually the game keep rolling, and if squids, they die, if shark then it stays. explaining why you see so many sharks in the river.

As for Sea lions, it is also kinda related to the spawn cap thing, but in a different way. I'm guess it's because the other mods also add creatures to the beach biome, so it makes it less likely that the game would roll and spawn sea lions.

I suggest using a mod to tweak spawnrates to all the mobs, if you want to sort this out, mods like spawn balance utility is handy for solving these issues, it's not really an issue with Ben's sharks, it's more of a quirk with Minecraft spawning mechanics.

I'll try that mod you recommended.

Okay, I tried it and sadly it doesn't seem to help with the Sea Lion spawn.

I also tried disabling Alex's Mobs and Fintastic and other mobs that add biomes and modify world generation, and still no Sea Lions have spawned :(
