To clean the inner wall of the fish tank, you need to fish out the fish in the tank first, then empty the water, and use a soft cloth to wipe off the algae and other dirt attached to it. If the attached algae is relatively strong, you need to use an algae scraper to scrape it off.After cleaning, we need to re-inject water, we must use trapped water, so that we can continue to raise fish, if it is new water, it may be harmful to the health of fish.
1. Scavenger: Scavenger is the most common clean fish. It is a benthic fish with its mouth on the bottom, which is convenient for it to suck the residual bait on the bottom of the water, so as to better maintain the water quality.It should be noted that the scavenger can not improve the water body, because it also has excrement, so it still needs to strengthen filtration, or clean up the dirt at the bottom of the tank when changing water.
2. Black-lined flying fox: Black-lined flying fox is known as the king of algae-eating fish. It mainly feeds on the algae on the wall of the tank.However, this kind of fish will also eat artificial feed, and if they are used to artificial feed, they may not eat algae.In addition, it can not be raised alone, because the courage is relatively small, there is no other fish, it will hide.
3. Kissing fish: Kissing fish, also known as kissing perch, is also a kind of clean fish.It can eat algae and moss, which is helpful to improve water quality.However, this kind of fish will eat more when they grow up, and their excrement will also increase, resulting in water pollution, so it is not a particularly good choice.
