How to Build Mixed Aquariums with Axolotls, Fish, and Squid

In an unmodded game, placing axolotls in a decorative pond or aquarium alongside other aquatic life results in the axolotls quickly killing every passive water mob in the tank. The Wilderness Truce Mod changes aquatic behavior so you can build lively, mixed-species water features.

Combining Aquatic Mobs Safely

With the mod's truce active, axolotls coexist peacefully with all fish and squid types. To set up a mixed tank or natural pond:

1. Prepare Your Water Enclosure: Build your aquarium, lush cave pond, or coral reef area as you normally would, ensuring it is enclosed so mobs cannot swim away.

2. Add Fish and Squid: Use water buckets to place tropical fish, cod, salmon, pufferfish, or spawn in squid and glow squid.

3. Introduce Axolotls: Release your axolotls directly into the same body of water using buckets of axolotls.

You do not need to place glass dividers or barrier blocks underwater to keep the species apart. The axolotls will swim alongside the fish and squid without attacking them, and your aquarium floor will stay clean of floating raw fish and ink sacs.

Warning Before Toggling the Truce

If you ever use /trigger predator_toggle to re-enable predator aggression for another project in your world, remember that loaded axolotls in your aquariums will immediately begin hunting their tankmates until you toggle the truce back on.
