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. So what species of trash fish are there? Let's find out together.

1. Silver carp

Silver carp is a freshwater fish species with a bland, tasteless flavor, many bones, and coarse flesh; it is rarely eaten by middle-class families in our country, and its fishy smell is especially strong. In addition, farmers often spread chemical fertilizer into the water where silver carp are raised to spur the rapid reproduction and growth of plankton in the water, so it is best to eat this fish sparingly.

2. Catfish

This fish is the dirtiest, because it grows up in garbage piles, and the water quality is extremely poor, yet it tastes delicious, and it grows very quickly even in polluted environments. However, because catfish are especially dirty, eating too many may carry a risk of cancer.

3. Yellow eel

The yellow eel is actually the fish with the most parasites; it lives beneath the mud, which is itself highly suitable for parasites to live in, and if it is not thoroughly heated, eating yellow eel may infect the human body with parasites.

4. Tilapia

Tilapia is an omnivorous fish that eats anything, and it has extremely strong survival ability; it can survive even at sewage outlets and can also help treat sewage. So while tilapia enjoys a good reputation, it is also listed as one of the "top ten dirtiest fish in the world." Imperceptibly, tilapia has been branded with the label "dirty."

5. Janitor fish

The janitor fish is affectionately called the "trash fish," but that does not mean the janitor fish diligently eats the garbage in the aquarium. The janitor fish is an omnivorous fish, and bloodworms, hamburgers, and the like are its favorites.

6. Walking catfish

The walking catfish has strong environmental adaptability and can grow and reproduce quickly even in sludge, so many people think it should not be eaten. In fact, there are two common types of walking catfish: one is the wild local walking catfish, and the other is the Egyptian walking catfish that has left people with a "dirty" impression.

7. Chinese high-fin banded shark

The Chinese high-fin banded shark usually feeds on brine shrimp, red peony, and some vegetables. The Chinese high-fin banded shark is an oviparous animal, but it has not yet been successfully bred in an aquarium environment; whenever a male fish approaches a female, it develops nodules on its head and fins.

8. Molly

The molly, also called the molly fish, is an omnivorous fish that likes to nibble on aquatic plants and the green algae on tank walls. In daily keeping, it can be fed artificial plant-based feed (live food), and can also be fed some fresh spinach leaves or lettuce leaves.

9. Albino Corydoras

The albino Corydoras is native to the waters of South America. Its body surface is milky white, its red eyes are clearly visible, and it has a mild temperament and can be kept in groups. It is omnivorous (live bait or artificial pellet feed), oviparous, and can be kept together with small fish.

10. Arowana

The arowana has a fierce temperament and mainly preys on live fish and shrimp, aquatic insects, frogs, and so on. When keeping it, you need to achieve dry-wet separation, and remove the bait residue and fish feces as much as possible, thereby reducing the ammonia content in the water and maintaining water quality.
