Target Selectors
Before we finish discussing data tags, let’s quickly explore how to use the @e target selector. The @e target selector allows you to target entities in your commands. If you use the type=tropical_fish value, you can target tropical fish:
@e[type=tropical_fish]
Target Selector Examples
To change the nearest tropical fish to a White/Orange Clayfish:
/data merge entity @e[type=tropical_fish,limit=1,sort=nearest] {Variant:16778497}
To kill all tropical fish:
/kill @e[type=tropical_fish]
