All the Ways to Get a Bucket of Tropical Fish
The first and most straightforward way of getting a Bucket of Tropical Fish is to catch some Tropical Fish in a Water Bucket. Firstly, use an empty Bucket on some water to fill it up. Next, swim up to any Tropical Fish and use the Water Bucket on them to scoop them into it. Following this, you can feed the Tropical Fish that you caught to an Axolotl by using the Bucket of Tropical Fish on your amphibious friend.
Where Tropical Fish Spawn
Tropical Fish can spawn in Lukewarm Ocean and Warm Ocean biomes, in addition to the “Deep” variants of both. Overall, the best place to find Tropical Fish is in a Deep Warm Ocean biome, as they are guaranteed to spawn there.
