Can the scavenger fish eat?

Scavenger fish is the common name of the multi-spoke-winged catfish and lower-mouth catfish of the subfamily Clariinae, also known as sucker fish, junk fish, etc., originally from South America with complex patterns, it is generally raised as an ornamental fish after it was introduced into our country. for foodie, we do not pay much attention to the ornamental value of scavenger fish, but the question of whether scavenger fish can be eaten. Let's take a look!

Can the scavenger fish eat?

Scavengers can eat fish. Scavenger fish is native to Latin America, where scavenger fish can grow up to be very large, and used to be a local edible fish. However, due to the exoskeleton fish, more bones than meat, nutritional value is not high, and there are more bacteria in the abdomen, smelly, so we are not recommended to eat.

What does the scavenger fish eat?

Scavengers are omnivorous fish, sucking algae, benthos and garbage in the water, and can also devour fish eggs and fry in large quantities. In the aquarium, it is often adsorbed on stones and glass to stabilize the body and suck algae, and it is also looking for benthos (such as water earthworms). Small pellets of feed floating on the water surface will be sucked upside down by belly, and the mouth is like a vacuum cleaner. Fish dung and green plants are all sucked into the stomach. There is also a bubble in the mouth, which is filled with oxygen and can be in the water for a long time.

How do you keep the scavenger fish?

1. Water quality: the water quality of artificially raised tropical fish is soft water or low hardness water, and the pH value is weak acid or neutral. Strong acidity, tropical fish breathing difficulties, slow growth, strong alkalinity, tropical fish Gill tissue 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 should be 1 / 4 of the amount of water in the tank, and then add the same amount of fresh water 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 water change should take out all the equipment in the fish tank, remove the water plants and fish, put them in other containers at the same temperature as the original water, scrub the cylinder wall and bottom with a sponge and change the water every 3 to 4 months.

3. Water temperature: tropical fish are extremely sensitive to temperature. If the temperature is not suitable, they will die quickly. Different species of tropical fish have different requirements for water temperature. Most tropical fish should have a water temperature of 20-24 ℃. During the breeding season, the water temperature should be 25-28 ℃, and the temperature difference between day and night should not exceed 4 ℃.

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

5. Lighting: put a fish tank in a sunny room, preferably in the morning and evening when there is not enough sunlight, each receive about an hour of sunlight. If you install a fish tank in a room without sunlight, you should use light to illuminate aquatic plants. Use 60 watts of incandescent bulbs or 40 watts fluorescent lamps for 6 hours a day. Light can make tropical fish grow faster and make the fish more colorful.

6. Stocking: the stocking density of tropical fish in the tank depends on the size of the tank. For people who raise fish for the first time, the smaller the density, the better, and need to be equipped with an inflatable pump. Quiet fish can not be mixed with aggressive fish, and large fish can not be mixed with small fish. There are a variety of feed options for tropical fish, such as fish insects, red insects or packaged feed suitable for different kinds of tropical fish. Raw baits and live baits should be washed to control the source of the disease.
