There are many kinds of tropical fish, so the breeding time is not fixed, generally ranging from 30 to 60 days. Take guppies as an example, when they are 3-4 months old, they can reproduce once a month, at least five at a time, and as many as 70-80. Zebrafish can reproduce faster, every 7 days, and about 6-7 times a year.
1. Parent fish pairing: When tropical fish reach the propagation period, they will pair first. The fish can be mixed according to a certain proportion of male and female, so that they can pair by themselves. After pairing, the parent fish will generally swim together and feed together. At this time, they can prepare for propagation.
2. Put into the breeding tank: Put the paired parent fish into the special breeding tank. The purpose of this is to isolate them from other fish so as to avoid being attacked during the breeding period. At the same time, it also gives the fish eggs a separate space for hatching. Some aquatic plants can be put in the tank to facilitate the attachment of fish eggs, while raw water should be used, otherwise the parent fish will feel uncomfortable.
3. Mating and spawning: After mating, the parent fish will soon lay eggs. Generally, the spawning is carried out in the evening. When the eggs are found, the parent fish needs to be fished out to prevent them from swallowing, so that the eggs can be hatched slowly in the tank. The parent fish should not be put back to the original tank in a hurry, first raised alone for a period of time, and then put back after recovery.
4. Larval growth: It usually takes several days for the fish eggs to hatch. Do not feed after hatching, wait 1-2 days, then feed migratory water or fish and insects, you can also use cooked egg yolk as bait, but do not put too much, otherwise it will pollute the water quality.
