Breeeding Oscar Fish
The Oscars, or Astronotus ocellatus, from Cichlidae family, are fairly easy fish to breed. All you need is pretty much leaving them alone and letting them do their thing if you lucky enough to get a pair. If not, breeding might be very hard. They are a very long-lived fish, probably one of the reasons they are so popular today. Originally from Amazon.
Oscar Fish obviously requires a large tank due to their large size. They prefer clean and clear water with a deep sand bottom, and a few large rocks. If you keep plants with you Oscars they will be dug up however there are some people that believe that Oscars like to have plants that they can dig up in the aquarium and this might be true since many large cichlid like to have toys when kept in aquariums not to get bored. And since Oscars are large and very smart cichlids, you can actually teach them tricks, they might want something to do like digging up plant.
Be careful, they are enthusiastic eaters and they love to eat smaller fish. Thus, only keep them with other fish that are of the same size. Temperature is important, and should be kept stable somewhere in 79-86
