I haven't talked to you about scavenger fish in a long time. The scavenger fish we see above the aquarium ornamental fish market is actually black and ugly, and then the mouth is like a suction cup, which is what we often call the scavenger fish.
If you have an ornamental fish, friends who have been around for a long time should know that this so-called scavenger fish is not really a scavenger. Because they don't eat fish feces in fish tanks, they just eat food scraps at most. So it's almost impossible to expect them to help us clean the fish tank.
In fact, the scientific name of this fish is lower mouth catfish, its origin is in South America, is now often called a kind of heterotyped fish. It's just that this catfish is less ornamental than other members of their family.
Because the other fish in the alien fish family are really too good-looking, like some crown leopards, snowflake aliens, labyrinth aliens, bearded fish, etc. have a certain degree of ornamentality, and the price is not low. But only this kind of lower catfish, although it is also an alien fish, but the appearance is indeed very average, but the number is very large. So some people who were more business-minded at the beginning packaged them, and when they saw that their mouths were like a suction cup, they would also stick to the walls of the glass tank, so they packaged them as "fish tank scavengers".
Later, this kind of lower catfish flowed into Our Territory in Large Quantities, including all parts of the world. At first, they were very popular because people didn't know it yet, and thought they could really help clean the fish tank. So I bought a lot, and after a long time of raising, I will find that this kind of fish tank is not only not clean. Instead, they will go to harass the ornamental fish that rest normally at night, to nibble on their scales, causing a very bad impact, and then abandon them directly in the wild rivers and lakes.
Don't lose don't know, throw a frightened. Because this fish is so strong in its vitality and very greedy, basically where they exist, some of the eggs laid by local native fish are eaten by them. Some sick fish are directly killed by them due to their limited physical strength. What is even more frightening is that because the local water quality environment is more suitable for their growth, they reproduce in large quantities, which has caused species invasion in many places. It has seriously affected the growth of some local native fish, causing more serious environmental problems.
What is the article that I want to remind everyone of here? I just want to tell you that I correctly understand the true identity of this fish, and then determine whether to raise it or not. Because after all, this kind of catfish is still a kind of ornamental fish, if it is raised well, it is still very stated and more ornamental. But we must not mistake it for really helping us clean the fish tank, after all, raising ornamental fish wants to raise the fish in a good state, want to have a cleaner fish tank, or rely on our usual more diligent to carry out daily maintenance of the fish tank.
So we must not pin some of our expectations on such a fish. If they are really raised, they will be raised as ornamental fish, and if they have been raised, they should not be casually thrown into the wild, so as not to aggravate the situation of species invasion.
Here is fish farming, if you also like to raise ornamental fish, you may wish to start a finger to pay attention, all the fish farming knows is here!
