Killifish
The killifish we commonly call is a huge family in the order Ginkgoidae. It is one of hundreds of species of oviparous minnows in the family Medakaidae. In a broad sense, it includes oviparous killifish and ovoviviparous killifish. Not all oviparous killifish have a lifespan of only one year. Most oviparous killifish can live up to 12-16 months in artificial aquariums.
1. Basic requirements for killing killifish in water
" V% }8 ~! I( a& Z%o t* ?Generally keep the water trapped for 5 to 7 days. If there is sunshine, it is best to let the sun shine in the water. Keep the fish in neutral soft water and a common water temperature throughout the year. The best water temperature is between 26 and 28 degrees. The perennial water temperature is between 22 and 26 degrees. The pH value is between 6.5 and 8.

Water quality requirements are the same as above. The hatching time of each kind of fish is different. Generally, we can see two small eyes inside the eggs. This has already proved the degree of hatching of the eggs.80% to 90%, indicating that it is possible to hatch, it is generally more suitable to use a fresh-keeping box for hatching, because the box is relatively small, it is easier to find young shrimps to eat after hatching, and there is no need to feed them. The New Year shrimps should be placed in a bright enough place. Generally, fill the crisper with 70% water, put a drop of potash in it, and then pour the eggs and peat soil away. It takes up to 10 hours for the eggs to hatch. If the fish eggs have not hatched after 10 hours, you may wish to collect them and wrap them in small paper with enough density to absorb them into the peat soil with a towel. The optimal hatching water temperature is about It must be hatched just now, otherwise the fry will not be able to eat it.
3. What points should be paid attention to in the usual management of killifish fry
(1) Every day, clean the residue in the box and the seepage of the fry. If possible, put 3-4 small snails in the box for raising the fry. (Cleaning method: straw, transfer fish to other boxes)
(2) Change the water once every two days, changing one-fifth of the water every time.
(3) Fry should not be raised too densely.
(4) Fry growth status: Generally at 6 dawn, you can use a larger tank to raise fish. After dry filtering, a small part of the male fry will start to develop color at 25 dawn, and the body color of the fry will become brighter at 60 dawn.At the dawn of 90, it begins to mature and breed the next generation.7
In addition, the newly hatched fish is the most difficult Now, many friends who have just come into contact have the most headaches at this stage, because opening is a big problem. The small fish come out very small, and most of the rare live bait cannot be eaten, causing the small fish to be unable to eat items. sacrifice. I feel that the best opening bait is migratory fish. All killifish can be opened successfully without harming small fish or affecting water quality. Vinegar worms are also relatively small bait. The advantages are that they are cheap and the worms like to swim and small fish like to chase food. The disadvantages are that they are difficult to separate and grow slowly. There are also new year shrimps. New year shrimps must use newly hatched shrimps. Most killifish can still be opened successfully. Separating the shrimps and egg shells requires careful skills. Excessive egg shells will cause the death of small fish and separate them. Be careful not to make exceptions. There is also egg yolk powder that can be used when the above-mentioned baits are not available. It can temporarily supplement nutrients for small fish, but it has a serious impact on water quality and must be cleaned up immediately after feeding. There is also vitamin B12. It is said that it can be supplemented by small fish, but I have not found any actual effect.
It is very important to feed the opening bait immediately after the small fish come out, otherwise the small fish will Fish are quickly sacrificed. After the small fish come out, they basically rest at the bottom of the water. They can swim horizontally after a few hours. This also depends on the fish's constitution. Some can swim normally soon after hatching. Small fish are generally interested in live bait. Strong fish will automatically pounce on live bait and stop eating when they are full. There is no need to worry that small fish will be strangled to death. If you feed water worms or vinegar bugs, you can see your belly turning white and feeling full.If you are full, if you feed new year shrimps, you will have an orange belly. Insist on feeding several times a day, and check every time to see if there are any small fish that do not eat. If it does not eat every time, take care of it alone. Use a straw to suck out the remaining bait immediately after feeding, otherwise a lot of flocculent items will be produced.
