 +To make the custom fluid behave like water or lava, you must add it to a corresponding fluid tag: make a file "data/minecraft/tags/fluids/water.json" and write identifiers of your fluids in there:
 +<code json>
 +{
 +  "replace": false,
 +  "values": [
 +    "modid:acid_still",
 +    "modid:acid_flowing"
 +  ]
