1. Morphological characteristics: The scavenger refers to two kinds of fish, namely, the multi-spoke pterostigma catfish and the lower mouth catfish. This kind of fish has a streamlined body, small eyes, a lower mouth, upper and lower lips with petal teeth, and a brush shape. It has black stripes, pectoral fins that make sounds, and two dorsal fins.
2. Living habits: Scavengers are native to Latin America. Their mouths are like suckers. They can swallow garbage at the bottom of the water, so they can be used to clean fish tanks. Usually it will be adsorbed on the stone to stabilize its body, so as to facilitate food intake. In addition, it will rest during the day and carry out activities at night.
3. Introduction to feeding habits: The scavenger is an omnivorous fish. Generally, it feeds on algae, benthic animals and garbage in the water. It also swallows fish eggs and fry. Therefore, it cannot be mixed during the breeding period. In addition, if a fish is sick, it will also adsorb on the diseased part of the gnawing, at this time they need to be isolated, so as not to cause greater losses.
The scavenger cannot live after being dried in the sun. Although scavengers are more vigorous than ordinary fish, it is impossible to live after they are really dried. But because of its hard body and flat body, when the skin is dry with a little soil, it looks like drying. Usually, after more than 12 hours away from water, the probability of survival is very slim, and 24 hours is dead.
