Molly Fish Fact and Information You Need to Know

  1. molly fish is the easy-going fish for beginners and usually quite cheap than other fishes easy to buy from any local store.
  2. They are omnivores that’s why they like flakes freeze or dried foods or live foods are more preferable for them
  3. The molly fish is the tropical fish that’s why it is recommended to add little amount of salt in the water. If you are keeping 10-gallon tank you must add 2 teaspoons of salt into it which is very great for them.
  4. It is cheap but very attractive tropical freshwater fish that is available in different color patterns like orange white diamond black and green.
  5. They are schooling fish and prefer to live in large community tanks but one thing is to care that you must keep an eye on if they combine with other fishes in the tank.
  6. Molly fish can only live with the live-bearing fish like the platy, guppy, and swordtails.
  7. The most popular varieties found in the market are sailfin dalmatian and balloon molly fish.
  8. The fish known as a “Mollie” used to be named Mollinesia but is now part of Poecilia. There are about 5 genuine species. Some breeders have altered their genes, which I abhor.
  9. While Mollies are mostly vegetarian they will pick at almost any plant in an aquarium and will damage many of them. Like most fish, they tend to eat any small animal that they can swallow, like brine shrimp.
  10. They are a South American (Mexico) tropical fish. Some of them live in brackish water and while they tolerate an amount of salt, it is definitely not required. Too much salt will kill the plants and prevent other species from living well.
  11. I dislike the colored patterns and the recent odd fin types like the lyretail. Those lyretails are like long hair and tend to become damaged easily. When I see spotted mollies, that suggests gene damage to me, not a desirable trait.
  12. The larger species of the SailFin Mollie is almost impossible to find. I had some in the 1970s and have been looking for them ever since. Occasionally someone advertises that they have them, but this is almost always false.
  13. I find the natural coloring of a genuine molly to be very pleasing. The scale has a wide variety of hues of blue and green. An adult Sailfin can reach 7″ in a large tank. Most are raised in tanks that won’t promote this size. A 4″ Molly would be unusual these days.
  14. Like most animals schools of mollies are socially orient. The larger males will kill their rivals by harassing them to death. There will generally be one or two young ones that stay out of the way and try to breed when they can which the dominant male might not kill outright. Once the dominant males weaken, the next rival will take over.
  15. Molly females retain sperm and can have hundreds of fry from a single insemination. As the females get larger they produce smaller and smaller fry and can deliver upwards of 200 at a time.
  16. It has the HUGE dorsal fin that is carried by the male in two of its variations. The Sailfin Molly can have a dorsal fin that is 1.2 times the height of its body vertically. The largest species has a fin that is often 1.5 times as high or even higher.
  17. During courting the male will fan out this dorsal fin and use it to intimidate the female until she’ll tolerate his attention. The males deliberate damage each other fins when they fight, which is quite often.
  18. I wouldn’t say that mollies tolerate other species, it’s more than they ignore them. I’ve seen them peck at others in an irritated manner while making no serious attempt to harm them as they do each other. Females can also show irritation toward each other. When the newborn fry is small, some mollies will eat them. So many keepers isolate the gravid (this is the term for the black spot that develops in a pregnant female) females to try to save as many of the young as possible.
  19. In a healthy tank, they will soon produce far more fry than it can support. The genuine species breed true. The altered ones do not. Many mollies sold as the Velifera, are not that species.
  20. Breeding aged males have their heads and under the mouth, areas turn bright orange.
