Future MC 1.12.2 0.2.02 in an ocean biome with b.o.p installed thousands of fish spawn in a very small area as soon as you get near the water, if you jump in so many spawn the computer starts to freezeframe and all you can see is fish. render distance of 8 and there must be close to 100,000 fish on screen with a ratio of 2:1 cod to salmon. You look in from a hill and the ocean is just fish. Had to disable fish in the config as the server was unusable due to lag. I'm surprised nobody else has come across this.

massive fish spawn rate is caused by randomtweaks, unsure what about it causes the massive spawn rate but my guess is something to do with the squid tweaks done to it. randomtweaks is opensource which is good though

I've linked this over to the Random Tweaks repo.

The squid spawning tweaks specifically only touch entities of the EntitySquid class, so I'm not sure if that's the problem. Regardless, does the issue persist when the squid spawning tweaks are disabled? (Set maxPackSize and spawnRadiusLimit to 0)

I encountered the same problem on a pack with RandomTweaks and Future MC plus various other mods.

I can confirm that setting maxPackSize and spawnRadiusLimit to 0 did fix the issue for us.

However I will say that after runnning LagGoggles, there are still too many tropical fish entities ticking on the server to my liking, so it would be nice if FutureMC had per chunk per player spawn limits for the fish by default.

Too many fishes lags my internal server, so I have to reduce fish spawn rate until it has been fixed.
A spawn cap for fishes is absolutely needed.

And a separate spawn cap for squid as well just like in 1.16.

There is a config option for fish spawnrate @Blue-Beaker

Further investigation shows that turning off Random Tweaks squid changes has no effect on fish spawn rates. I'm still getting hundreds of fish in an area.

Sorry if my post was misleading, I realize now that as I was uploading the config for the server, my friend uploaded an InControl file to limit the spawn rate at the same time, and because of that I thought the RT config tweak fixed it.

Sorry about that.

There are several issues on the In Control repo about it seeming to cause mob spam. I'm starting to think this may be a Vanilla issue that is being triggered by certain mods that manipulate spawn rules.

I have found a janky solution.

People have experienced this, but I haven't found a solution for it.

No problem I installed 'in control' and have configured the spawn rate through that I reduced it to 15 per chunk per player. And it seems about right now. I have noticed that no items drop when killing the fish and when listing all items from your mod there are no items for the fish apart from the fish in buckets was this an error? Or were they not supposed to drop anything?

Thanks for getting back to me I love the mod I've installed it for as long as I can remember on my personal server thankyou for all your effort.

I forgot to add their drops.

Although I have seen the bug first hand, it seems that I can no longer reproduce it. I'm thinking it's a certain combination of mods that cause it, but I tested with my personal modpack and fish were spawning normally.

As a temporary fix the mod 'in control' worked perfect to reduce the spawn rate I also configured the loot drops so everything works correctly now. If you would like i can send you a copy of the config files for it that i have made to get you on until the bugs are worked out in this mod. Steve

@steve13689 yes please

I'm having the same issue, and I use cubic chunks... along with about 400 other mods but this mod spawn so many fish it kills my fps /killing all these fish is murder on my system in and of itself.

No problem mate heres my configs and the mod im using if you have any issues or cant download the files let me know.

Hey, I've experienced this same issue, I have less than 30 mods when this happen so this might help you to find the cause : https://pastebin.com/8khV7W5i
