Oscar breeding?

Post by starfang on Mon 14 Jun 2010, 00:05

Can some one tell me more about this?
I have two oscars. how can you tell if they are a male or a female? Mine seem to "flirt" the way I have seen other fish, but how can I know for sure? What types of things and conditions would they need to breed?
Both of them are already about 4 inches long and do a lot of rubbing together.

Found this,..

Breeding Oscars. You won’t breed them in a 10. You need (minimum) a 55-gallon tank (70 gallons would be better). In fish farms they use a large diameter concrete pool two feet deep -- very similar to a kid’s wading pool in a public park, but with steep sides. They put in lots of large oscars and let them select their own mates. The breeder adds several large pieces of slate (some on the bottom, some leaning against the sides). The slates are checked frequently for spawns. Slates of eggs are removed and hatched artificially under controlled conditions. You can get bit walking thru these breeding ponds -- especially when extracting egg-filled slates.It is difficult to identify the sexes of Oscar Cichlids.

Breeding Tank. In your breeding tank partially bury a large slab of slate. Let them dig it out themselves. (If they spawn on the filter plate, the eggs and fry get sucked under.) Take out the eggs. Do it at night, if you fear oscar hickies. You will have better results rearing the eggs artificially.

Oscar Eggs. Put the slate in a well-filtered 10-gallon tank and add a slow bubbling airstone as their surrogate mama. Add methylene blue to taste (circa 2 ppm). Most cichlid eggs are clear or a light amber color. Oscar eggs are a cloudy off-white nearly tan color. As they develop, a line divides the eggs in half. They hatch in three to seven days depending upon temperature.

Hatched Eggs. Oscar eggs hatch into an eyeless blob with a wiggling tail attached to the slate by an unseen thread. They look nothing like oscars (or fish). As they absorb their yolk sacs, they lose their sticky thread and fall to the bottom in a sticky clump. Most cichlids absorb their yolk sacs fairly quickly and turn into hungry baby fishes. Oscars take much longer and grow into much larger and hungrier fry. Once they grow eyes and fins, they will start swimming (and eating). They cannot eat until they become free swimming.

Oscar Fry. Very small oscars sport a black line down their sides (typical of predator fishes who tend their young in schools). If you’ve ever seen a male largemouth bass tending his pit of fry, you’ve seen the obvious relationship between our North American centrarchids and the South American cichlids. Oscar fry eat newly hatched brine shrimp – lots of it and often. You will not believe how much they can eat. You will need to change their water often.

Sexing. They are difficult to sex. The easiest method is to obtain six to eight juveniles and let them pair off on their own as they reach sexual maturity or Only when a female is about to lay, does it become evident that she is a female as she becomes somewhat plumper than the males.

Welcome to APU got any pics of your Oscars?
