What does the scavenger fish eat? How do you raise it?

The scavenger fish gets its name because it likes to eat residue and dirt, so it is easy to survive and easy to raise, so it is welcomed by farmers. So, today the editor will introduce to you what the scavenger fish eats? How do you raise it? Let's get to know it together.

What does the scavenger fish eat?

Scavengers are omnivorous fish, suck algae, benthos and garbage in the water, and can also devour fish eggs and fry in large quantities, so it is necessary to put more aquatic plants to cover the mixed culture of scavenger fish and other fish species. Scavenger fish are often adsorbed on stones and glass and suck algae in the aquarium, and they are also looking for benthos (such as water earthworms). For small pellets of feed floating on the surface Will use the belly upside down to the surface of the way to eat, the mouth like a vacuum cleaner, the fish dung, green plants all into the stomach, the mouth also contains a bubble, this bubble is oxygen, can be in the water for a long time.

Second, how to raise the scavenger fish?

1. Water quality

Water quality is the most basic place for breeding. Artificial breeding of scavenger fish requires soft water or low hardness water, weak acidity or neutral acidity, strong acidity, dyspnea, slow growth and strong alkalinity. Gill tissue of the fish will be corroded.

2. Change water

Part of the change of water is to suck out the feces, residual bait and other dirt from the bottom of the fish tank with a straw, and the amount of water absorbed is 1 to 4 of the amount of water in the tank, and then add the same amount of fresh water which has been dried or chemically dechlorinated at the same temperature. the frequency of mixing water is 2 times a week in autumn and winter and 3 times a week in spring and summer. All the equipment in the fish tank should be removed, the water plants and fish should be removed and placed in other containers with the same temperature as the original water. Scrub the cylinder wall and bottom with a sponge and change the water every 3-4 months.

3. Water temperature

The suitable water temperature for scavengers is 20-24 degrees, 25-28 degrees during the breeding season, and the temperature difference between day and night should not exceed 4 degrees.

4. Oxygen

Breeding scavenger fish should plant a certain number of aquatic plants in the fish tank. Aquatic plants will produce oxygen during photosynthesis, which will increase the oxygen content in the water. At the same time, timely removal of dirt and frequent water change can also increase the dissolved oxygen in the water.

5. Lighting

Breeding scavenger fish needs a certain amount of light, and a fish tank is placed in a sunny room, which is best exposed to about 2 hours of sunlight every day. If a fish tank is installed in a room without sunlight, light should be used to illuminate aquatic plants. Use 60 watts of incandescent bulbs or 40 watts fluorescent lamps for 6 hours a day.

6. Fish tank

The scavenger will not be small when he grows up, so it is recommended that the fish tank should be more than 50 centimeters. It is omnivorous fish, and blood worms can be used for general family farming. If it is a better species of scavenger, you can use working feed, and also draw water, earthworms and other feed, as well as algae, moss and weeds on the fish tank. In addition, the scavenger fish also like sunken wood decorations, if possible, buy one and put it in the fish tank. Make it more adaptable to the environment.

7. Stocking

For people who raise scavengers for the first time, the smaller the density, the better, and they need to buy an inflatable pump. If they are skilled in culture, they can raise them in a larger fish tank.

The above is about what the scavenger fish eat and how to raise it. I hope it can help you!
