what is the different between and female and a male oscar fish?

Answer 1

Oscars are very difficult to sex. Males may be slightly larger and the fins may be slightly elongated too but not by much. Experienced cichlid keepers look at the ventral openings and refer this as "venting". You are looking for differences in the actual openings. Females would have a larger opening to lay eggs. Males would not need such a big opening so it is smaller. Since Oscar eggs are very small it is not a very reliable way to tell the sexes apart. Bottom line -almost impossible.

I only have one male oscar now. I had another male and one female a few years ago. They are hard to tell apart- impossible when their little, I think. The males are wider from the top to the bottom then the females. I don't know if you understand what I am saying. If they are sideways in the tank- head here and tail at the other end. The width I am talking about is from their back to the underside. Their back is what faces the top of the tank, the underside faces the gravel at the bottom. Females are not as wide as the males. They have to be fairly large to see the difference. I love Oscars- mine is 5 years old his name is Joe.

Answer 3

No well defined external differences are discernable for male and female oscars although males tend to be larger and more colorful. Breeding oscars defend their spawning sites, nest, and young quite fiercely. Male oscars may lock jaws in disputes over territory or mate selection. In captivity male and female have been observed to jointly prepare the breeding site. Eggs are adhesive and laid on a flat open surface cleared by the breeding pair. Hatching of eggs is temperature dependent, but typically occurs within 3 to 4 days. A single spawning may consist of as many as 1000 - 2000 eggs. Like most cichlids, oscars tend and guard their young. Non-native populations in South Florida are observed to spawn primarily during summer months.

Answer 4

seen identity of intercourse in keeping with any exterior features is amazingly confusing. countless theories which incorporate ranges of color and aggressiveness, the form of the top, spots or shade on the tail or gills, and others have all been tried, yet with constrained fulfillment. the only valuable thank you to intercourse an Oscar is to seem below the fish. To the rear of the fish's anus, is the intercourse organ. interior the ladies individuals, that could be a small hollow. interior the male, that could be a phallic performing outcropping. although, those at the instant are not without issues great without magnification, and preserving a fish the different way up under a magnifying glass is confusing at best.

Answer 5

Sexes are only distinguishable at spawning times when the female has a more obvious, rounded genital papilla.
