Editing Livebearers (section)

==Common aquarium livebearers==
<!-- These aren't common and should not be listed under common! And not all sharks and rays are livebearers. The [[coelacanth]], [[Embiotocidae| surf perches]], and many types of [[shark| sharks]] and [[Batoidea|rays]] are all livebearing fish, aquarists do not usually keep these.-->Species of interest to aquarists are almost always members of the family [[Poeciliidae]], most commonly [[guppies]], [[fancy molly|mollies]], [[Platy (fish)|platies]], [[Xiphophorus|swordtails]], [[Poecilia wingei|Endler's livebearer]], and [[mosquitofish]]. Most of these are [[ovoviviparous]], with the developing embryos receiving no nourishment from the parent fish, but a few are [[viviparous]], receiving food from the maternal blood supply.<ref>{{Cite web |title=Livebearing Aquarium Fish—Habitat, Diet, and Breeding |url=https://www.thesprucepets.com/livebearing-aquarium-fish-1378599?utm_source=chatgpt.com |access-date=2025-05-15 |website=The Spruce Pets |language=en}}</ref> 

Because the newborn fish are large compared to the fry of [[oviparous]] fish, <!-- Added clarification to oviparous.-->which are those that lay eggs, newborn fish of livebearers are easier to feed than the fry of egg-laying species, such as characins and cichlids. This makes them much easier to raise, and for this reason, aquarists often recommend them for beginning fish breeder hobbyists.<!-- Minor language changes and clarifications added.--> The larger livebearer fry makes them far less vulnerable to predation, as the parents often eat fry if hungry. With the sufficient cover in the way of plants or porous objects, they can sometimes mature in a community tank.<ref>{{Cite web |title=Livebearers: Raise Guppies, Mollies, Platies & Swordtails in your Aquarium |url=https://www.liveaquaria.com/article/257/?aid=257 |access-date=2022-09-08 |website=www.liveaquaria.com}}</ref>
