Fish and Aquariams
open your inventory and select spawn ocelot then get raw fish and spawn the ocelot stand still until it walks up to you and give it the fish.
Salmon live in the ocean, but swim up rivers to spawn.
The goldfish and spawn need to be separated immediately spawning has finished otherwise the spawn will be eaten. I used to remove most of the spawn rather than moving the fish.
Get single player commands then type in spawn silver fish. Make sure it's not on peaceful.
