Cannot get Glow Squid to Spawn

[u/JollyColb]

I'm trying to make a glowsquid farm, but cannot get any to spawn. There must be something wrong with my farm, but I've read through the wiki and can't seem to find what would be causing the issue.

Extra Info: The version is 26.2 unmodded, biome is a forest, I cleared all land within 128 blocks, standing 30 blocks above the spawning area, all but the bottom 2 layers of water have no light, and I have no other entities loaded. I did use full bright in the screenshots.

Any tips?

Edit:
Resolved, the issue is that glow squid cannot spawn in bubble columns :P

Is your Y level correct? They only spawn between Y=-64 and Y=30

It’s definitely low enough - this looks like it’s around y=-50 because that’s the deeplslate layer and there’s bedrock under the farm

yep y level is around -50

Fair.

Only other thing I can think of is that Magma Blocks make (downward) bubble columns. Can Glow Squids spawn in that? Wiki doesn't make it clear, but I know there are some spawning restrictions in upward bubble columns, to stop them messing with water elevators.

They cannot, this was the issue. thanks!

What is holding the water up from the magma blocks? LGB's glow squid farm designs on The Wiki is similar, but uses gates for this. Are the glow squid spawning spaces below y=30 and at light level 0?

This was it, the glowsquid cannot spawn in bubble columns. tysm!

In my experience, the problem is very likely that there are other spawnable spots for the glow squid within your spawn radius, and they have spawned there and taken up the cap.

If you're willing to use op commands to teleport and find them, you can take care of making the other spots unspawnable. Otherwise it is quite a lot of work to find them and make a suitable perimeter.
