How to Keep Ornamental Fish? A Detailed Guide to Breeding Techniques and Precautions

Fish are a very common type of aquatic animal in daily life, and fish can be divided into many kinds; edible fish and ornamental fish are the two most common types. Nowadays people's living standards have improved, so they keep some fish at home for ornamental purposes. However, when keeping them, there are also many little tricks that need to be learned, and only by mastering them can you let them grow healthily.

How to Keep Ornamental Fish

1. If you are feeding ornamental fish for the first time, try to buy goldfish of the Wen variety, which have strong survival ability. This kind of goldfish is easy to keep alive, lives a long time, and is easy to raise.

2. Change the water in the fish tank in time. The water in the fish tank should be changed on schedule to keep the water quality clean. Note that when changing the water, do not replace all the water at once, because it is very hard for the fish to adapt to the new water quality, water temperature, etc., which can easily lead to the death of the fish.

3. Clean the excrement of the ornamental fish in the fish tank regularly to keep the tank clean. The waste excreted by ornamental fish pollutes the water quality quite heavily and easily breeds bacteria. Clean the excrement at the bottom of the water in time to ensure a good living environment for the ornamental fish. If conditions permit, you can install a filtration device, which is more convenient.

Ornamental Fish Breeding Techniques and Precautions

I. Breeding techniques:

1. Ensure the oxygen supply in the fish tank. Ornamental fish are very active and consume a lot of oxygen. If you want to ensure they survive for a long time, it is best to install an oxygenating device to ensure the oxygen supply in the fish tank.

2. Place a certain number of ornamental fish according to the size of the fish tank. Ornamental fish need a certain amount of space to survive so that they can move freely. Therefore, the number of ornamental fish to place should be decided according to the size of the fish tank; generally, a fish tank holding 100 liters of water can keep 10--15 fish.

3. Put an appropriate amount of stones, aquatic plants and the like in the fish tank. The growth of aquatic plants can provide a certain amount of oxygen for the ornamental fish and can also purify the water source.

II. Precautions:

Choose suitable feed and pay attention to the number of feedings and the method. When buying fish feed, choose products produced by regular manufacturers with qualified quality, so that after the fish eat the feed it is easy to digest and absorb and they do not get sick. When feeding the feed, note that during the day it is generally about 3 times, feeding once every 6 hours. At night, feed as little as possible.

Ornamental Fish Feeding Tips

1. Artificial bait for marine ornamental fish generally has iodine, seaweed, krill, brine shrimp and some plankton added to its ingredients. Floating bait is suitable for feeding fish that forage at the surface. Adhesive bait and tablet bait are suitable for feeding bottom-dwelling ornamental fish such as the catfish family and the loach family.

2. Generally feed about 3% of the fish's body weight in bait each day. It can also be estimated as follows: the daily feeding amount for a one-year-old ornamental fish is about equal to the size of its head. The daily feeding amount for a two-year-old ornamental fish is about 1/2 the size of its head. For ornamental fish three years old or older, their whole-day food intake is about 1/3 the size of their head.

Prevention and Treatment of Dermatomycosis in Ornamental Fish

Dermatomycosis, also called saprolegniasis, is an extremely common disease of ornamental fish. During capture and transport, the fish body is injured by external wounds or parasites, and after the fish's skin is injured, mold spores invade and cause infection.

1. Pathogen: aquatic molds such as Saprolegnia and Achlya.

2. Symptoms: white fuzz grows on the fish's body. In severe cases, the white fuzz can surround the fish's body. The fish becomes thin and weak and its swimming ability decreases. This disease can occur in all four seasons.

3. Prevention: as long as you are careful during capture and transport so as not to injure the fish body, you can put a small amount of table salt into the aquarium where new fish are stocked to inhibit the occurrence of saprolegniasis, pay attention to cleaning and disinfection when putting in live bait, and keep the water quality clean to isolate the growth of aquatic molds; this can generally prevent the occurrence of this disease. Once it occurs, the following treatment methods can be used.

4. Treatment: soak and wash in 2%-3% salt water, once a day, 5-10 minutes each time. The specific remedy is a 1 to 2 parts per million (1-2 ppm) malachite green solution, soaking for 20-30 minutes each day. Mix 2 parts per million (2 ppm) potassium permanganate with 1% salt water and then soak the diseased fish for 20-30 minutes. Raise the water temperature to inhibit the growth of saprolegnia. And you can use a 15-watt ultraviolet lamp to irradiate for several hours each day, which can effectively inhibit and eliminate aquatic molds.

When keeping ornamental fish, be sure to change the water in the fish tank in time, and also clean the excrement in time; ensuring clean water quality is a very important step. There are also many tips for feeding; do not feed too much, and do not feed at night. These are all things to pay attention to.
