Live Bearers

Some excellent Aquarium Fish that can cause problems if they get into waterways away from their native area.

Having live young, as opposed to laying eggs, is a thing exploited by some members of every major class of vertebrates, except birds. No class of vertebrate does this exclusively, there are even some egg laying mammals, like the Echidna.

There are many types of fish that have live young. These come from many different groups For example, the Great WhiteShark has live young, but this is not a good fish for a mixed community home aquarium of small fish.

This article is about one group of live bearing fish, the live bearing tooth carps. This name is sometimes used specifically to refer to the Mosquito Fish. This is slightly misleading since the name "Live Bearing Tooth Carps" are a group of several species. The fish I am including in this article are the Guppy, the Endlers Guppy, the Swordtail, the Platy and the Molly. There are quite a few other species in the group which are also excellent Aquarium Fish.

Pest Fish

The Mosquito fish is probably the one type of fish which does more damage to the world's aquatic ecosystems than any other. Because of this and its aggressiveness in aquariums, I would only suggest it as an aquarium fish for the areas it is native to. This would help prevent its further release into unsuitable places.

Any fish introduced outside its natural area can cause problems and the live bearing tooth carps of several species have caused much disruption of ecosystems.

Teeth

The Live Bearing Tooth Carps have many characteristics in common. The teeth referred to should not be taken as meaning that they are vicious. The Mosquito fish is one of the few of this group I would class as aggressive.

Live BearingThese fish do not lay eggs, and have well developed babies. They are technically termed "Ovoviviparous." That is, the babies develop from eggs inside the mother, but do not receive mush nourishment from the mother, but live off the egg yolk. This is different from the placental mammals where the babies are nourished through the placenta from the mother. MatingFertilization is internal. The male has an anal fin modified to form an intromitent organ. It can be tilted forward to transfer packets of sperm, called spermatophores, into the female. She stores the sperm until it is needed to fertilize eggs. In some cases the sperm may be stored for up to 10 months, although 3 months is more common. This modified fin is referred to as a gonopodium. It is functionally similar to the penis of mammals, but is structurally totally different.This modified fin can be used to identify the sex of the live bearers. In males, the anal fin is long and thin, but in the females it is triangular shaped.BabiesYoung Live Bearers tend to be large compared with the size of the parents. This group of fish has sacrificed the very large numbers produced by many egg laying fish, and put more effort into each baby. The babies have a high survival rate.CannibalismMost live bearers will eat their own babies, as well as the babies of other types of fish. The babies that are better at getting away from their parents tend to be the ones to survive.SourcesThe Main Sources for this article are the fact sheets for the separate species: Guppy Fact Sheet, Endlers Guppy Fact Sheet, Swordtail Fact Sheet, Platy Fact Sheet, Molly Fact Sheet and Mosquito Fish Fact Sheet.
