Breeding skills of clown fish

Algae-eating snails, five-claw shellfish and so on are the same as the artificial reproduction of nine-hole shellfish that we eat every day, when the gonads mature, we can use simple warming method or cooling method to stimulate them to release eggs and semen. First of all, take out the mature breeding shellfish, the female-to-male ratio is about 1:3, use the heater or ice cube to slowly rise or drop the water temperature for about 4 ℃, then rapidly cool or raise the temperature for 2 ℃, and then put it back into the original tank and return it to the room, where a large number of white smoky sperm and egg particles can be seen. There are slightly more females than males in most shellfish. Take nine-hole shellfish as an example, the sex can be distinguished by lifting its mantle. When the males mature, the gonads are full or milky white, and the females are green or brown.

Clown fish is the most lovely group of coral reef fish, almost every beginner of marine fish will give priority to it, mainly because it is healthy, strong and easy to raise, the price is not high, and its special ecological behavior of symbiosis with sea anemones. Clownfish are hermaphroditic and male precocious fish. There are quite a lot of successful cases of reproduction in the aquarium, and there are also many professional breeding farms abroad, and there are many interesting phenomena of this kind of fish. For example, in a group of clown fish of the same species in the aquarium, there is only one male and the rest are females. When the male fish is removed, after a period of time, one of the female fish will turn into a male fish, and when the original male fish is put back, the transformed male fish will return to the original female fish state again!

If you also want your clown fish to have many children, you might as well try it in the following ways:

First of all, create a warm and comfortable nest for them. the way to do this is to find a few living rocks and build a cave with a natural barrier for them. you must pay attention to maintaining proper water flow, and it is best to put an oval pebble in the cave. there are pebbles affixed to the mouth of the cave, and then find a relatively large sea anemone, which can cover almost the whole mouth of the cave or cover the pebbles. The ideal sea anemone is a large carpet sea anemone or long-bearded princess sea anemone to provide safe shelter. Next, we select 1-2 smaller males (red clown males are bright red) and 4-5 mature females with larger abdominal gonads (red clown females are dark red). After feeding for a period of time, the pairing is observed. For example, most of the paired clowns are nestled together in the sea anemone, and the rest are driven away to prevent interference, while the rest of the clown fish can be removed. Then prepare a special food for them every meal, which can be mixed with VG- microbial nourishing agent and vitamin E in the bait.

Observation of various signs before spawning:

The main results are as follows: (1) when the gonads of male and female fish mature, the mating organ of male fish and the fallopian tube of female fish will protrude obviously.

(2) when the spawning period is approaching, there will be an interesting phenomenon. They will diligently organize their nesting environment and use their mouths to sweep away algae and gravel.

(3) most of the breeding farms are ripened by hormone injection, and the 24Hrs will begin to lay eggs after injection.
