[SOLVED] [1.8] How to Have Custom Mob Spawn in Nether Fortress

[Furgl]

I'm creating a custom mob and I want it to spawn in a Nether Fortress, the same way blaze, magma cubes, and wither skeletons do in vanilla. The normal way that I would add a mob spawn is using this:

EntityRegistry.addSpawn(Entity<Mob>.class, 15, 4, 4, EnumCreatureType.MONSTER, <Biome>)); 

but seeing as the Nether Fortress is a generated structure instead of a biome, I'm not sure how to go about doing that.

Thank you for the reply! I'm new to modding, so could you explain what you mean by:

I got it working as expected now, thank you diesieben07.

And I now have a basic understanding of how event handling works in Minecraft, thank you SanAndreasP.
