You may think a rainbow trout has a nice, clean, pink belly, but it can also be a cobic fish.
This fish has a white spot on its head, which is where the cobia bacteria can live and breed.
A cobic trout is often found in the wild, but the exact cause is still unknown.
The fish is also called rainbow trout because it is colored by the rainbow color.
The rainbow color is what attracts the cobic to the fish.
Rainbow trout are usually found in rivers, streams, and ponds in the United States.
Some fish may be found in salt marshes.
