What are the top ten trash fish species?
Trash fish are also called suckerfish, janitor fish, and so on, because they feed exclusively on the excrement of other fish, sediment at the bottom of the water, aquatic plants, and even mud; they have an excellent appetite and good digestion, hence the name "trash fish." Of course, some fish are raised in such poor conditions, growing in sewage, that they are also collectively called trash fish.
