How to raise Mary fish
Mary fish, also known as Molly fish, is called jasmine medaka. It is a kind of ornamental fish belonging to the family Linnaeus and medaka. So, how do you raise Mary fish?
First, how to raise Mary fish
1. Water quality
Mary fish like hard water, and although they can survive in the slightly sour soft water that most tropical fish like, they will be restless and restless, and once replaced with hard water, the number of jumps will be significantly reduced. It is sensitive to water quality and needs to change fresh water frequently.
2. Water temperature
Mary fish have a strong ability to adapt to water temperature, and they can even tolerate a low temperature of about 10 ℃, but this does not mean that they can grow well at this limit of water temperature, and it is also easy for them to get sick and die from mold infection for a long time.
3. Feeding
Omnivorous, love to eat algae, in addition to feeding crushed plant green leaves, but also can feed animal bait.
Second, the reproduction of Mary fish
After entering the sexual maturity period, Mary fish can give birth to larvae almost every 35 days or so. Because Mary fish is an oviparous fish, that is, after in vivo insemination, when the fertilized eggs are mature, they will directly produce larvae, so it is easier to reproduce. Only pay attention to the abdominal expansion and blackening of the female fish. At the same time, carefully observe the anal part of the female fish, if it is found that the spawning tube is punctate or obviously dragged out. The female fish will certainly give birth to larvae within 2-5 days, just put the female fish in the breeding tank alone. During this period, it should be noted that the water quality should not be changed too much. Drastic changes in water quality will directly lead to the premature birth of female fish, and the production of immature larvae or even undeveloped eggs. The number of larvae produced by Mary fish depends on the size of the female, and generally increases with the growth and development of the female, ranging from 40 to 100, and some fish can produce about 200 at a time. After giving birth, the larvae will swim by themselves after a while, and they will also prey on smaller water fleas, or they can also be directly fed with artificial bait with smaller particles.
