Janitor fish, also known as sailfin catfish, is an invasive species of catfish native to the Amazon Basin of South America. This species of fish damages levees, builds nests, causes erosion and competes with native fish for food. Although known as scavengers rather than predators, the fish they care for feed on small local fish and eggs. Algae, plant, and carrion-eating care fish food means that it is widely marketed as algae-eating fish in aquariums. They can grow to over 2 feet in their natural habitat and produce large amounts of waste that can contaminate the water, so most will eventually outgrow the aquarium. It's still sold for aquariums, but another use is emerging in areas with high foreclosure rates with pools. City authorities in areas such as Wellington, Fla. We put managed fish in the stagnant pool and clean the pool cheaply. A Filipino student, who was looking for a way to use farmed fish as chicken feed, found a way to use it to develop biofuels. He submitted his project to his Intel International Science and Engineering Fair and won his third grand prize. His experiments show a useful way to rid the Philippines of invasive fish that have been devastating fishermen's livelihoods by using them to create additives to diesel fuel that lower the price of oil. According to Dr. Jonathan Armbruster, a fish curator at Auburn University, controlled fish are edible unless they contain high levels of mercury or other metals. In the country of origin, it is eaten whole roasted or put into soup. In areas without refrigeration, captive catfish can remain wet for up to 30 hours, making them a good source of fresh food. Many fishermen use grilled care fish as an appetizer for drinks. The Southeast Asian Agricultural Graduate School Research Center has launched a program aimed at ridding wetlands of farmed fish by using them to produce fodder for livestock. Fishermen are paid to catch the fish they care for and process it into fishmeal, which is used as an ingredient in fish, livestock, or animal feed. It can also be used as a liquid fertilizer. Janitor's thick skin, especially the abdominal exoskeleton, can be tanned into fish skin and used to make items such as purses and purses. On the other hand, some species make great additions to your aquarium and they are caretaker fish. Janitor fish are a species of fish that do not have bright colors. They are very different from other species with an interesting and beautiful appearance. As you know, care fish are much darker in color and have extraterrestrial features. Some believe that the fish you take care of stays in the same position in the water. There are many situations going on around them, but they stay in one place. They also sometimes enter a corner. But they like the middle position, so go for it. For this reason, some people have removed the shelters that housed the caretakers, believing that they did not want to be in close contact with others. But this idea is wrong. Care fish move according to their mood and need. As you know, care fish are nocturnal creatures. They keep busy all night from dusk. They love to run around in shelters under burrows and on driftwood. Therefore, many people think that they are in the same position because they move at night when people are sleeping.
