How old can the scavenger fish grow?

Scavenger fish is a common mixed breeding aquarium species, known as the cleaner in the aquarium, because it is mainly fed with bottom garbage, algae, etc., through their treatment can achieve the role of purifying water quality, for other aquarium breeding to provide a healthier, cleaner living environment, let's take a look at how big the fish can grow!

How big can scavenger fish grow?

Scavenger fish can grow up to 250 mm in length under suitable conditions, and eat a large amount of fish eggs after adulthood. In addition to eating algae such as moss, they often eat eggs of other fish. They can eat 3000 to 5000 eggs a day, and they can also devour large numbers of fish larvae. At the same time, because it is an alien species, there is no natural enemy in China now, and it is easy to reproduce in large quantities in rivers, which will threaten the survival of local fish and destroy the ecological chain.

How long does a scavenger fish live?

Scavengers have long or short lifespans, not to say that they will live for a few years, as short as 1~2 years, as long as 6 years old, or even longer or shorter lifespans, but they are inseparable from the water environment. Many of the causes of death of scavengers were written in the column of starvation, especially for adult scavengers who ate greatly, but there were also cases of freezing to death. The environment was the most fatal for scavengers.

How to raise scavenger fish

1, water quality: artificial breeding tropical fish water quality requirements for soft water or low hardness water, pH to weak acid or neutral is good. Acid is stronger, tropical fish breathing difficulties, slow growth, strong alkaline, tropical fish gill tissue will be corroded.

2, water change: part of the water change is to use a straw to suck out the feces, residual bait and other dirt at the bottom of the fish tank, water absorption to 1/4 of the water in the tank is appropriate, and then add the same amount, the same temperature after drying or chemical chlorine removal of new water, the number of times to water twice a week in autumn and winter, spring and summer 3 times a week is appropriate. All the water should be removed from the tank all equipment, will be removed from the aquatic plants and fish, placed in other containers with the same temperature as raw water, with sponge will tank wall and tank bottom scrub clean, every 3 to 4 months to change the water once.

3, water temperature: tropical fish is extremely sensitive to temperature, if the temperature is not suitable will soon die, different types of tropical fish on the water temperature requirements are different, most tropical fish water temperature to 20~24℃ is appropriate, in the breeding period of water temperature to 25~28℃ is appropriate, day and night temperature difference can not exceed 4℃.

Oxygen: A certain amount of aquatic plants should be planted in the fish tank, because aquatic plants produce oxygen during photosynthesis, so that the oxygen content in the water increases. At the same time, timely removal of dirt, frequent water change, etc., can also increase dissolved oxygen in water.

5, lighting: in the room with sunlight placed fish tank, preferably in the morning and evening when the sun is insufficient, each accept about 1 hour of sunlight, if there is no sunlight in the room decoration fish tank, should use light irradiation plants, with 60 watts incandescent bulbs or 40 watts of fluorescent light every day for 6 hours. Light can make tropical fish grow faster and make fish more colorful.

6, stocking: tank breeding tropical fish stocking density depends on the size of the fish tank, for the first time fish, the smaller the density, the better, and need to add an inflatable pump, quiet fish can not be mixed with offensive fish, large fish can not be mixed with small fish. Tropical fish feed has a variety of options, such as fish worms, red worms or suitable for different types of tropical fish packaged feed, raw bait, live bait should be washed to control the source of disease.
