Tropical fish are common bucketable aquatic passive mobs found in warm or lukewarm oceans, mangrove swamps and lush caves. There are 2,700 naturally occurring variants of tropical fish of different colors and shapes with unique names in Bedrock Edition and 3,072 in Java Edition.[1]

In Java Edition, random varieties of tropical fish spawn in groups of 8 in lukewarm or warm oceans (as well as their deep variants) and mangrove swamps at Y-level 50 to 63, and in lush caves in aquifers at any Y-level. They are subject to fish spawning requirements.
