How do you vent Oscar fish?

Answer 1

To Vent an Oscar you must first remove it from the tank and turn it over onto it's back so it is belly up. You must then examine the Vent.

The Vent is the opening between the anus and the anal fin. This is where the male fish release their sperm and the female fish release their eggs. This area is also known as the genital papilla.

The female's Vent will be larger than the males to accomadate the passing of the eggs.

Unless you have one of the opposite sex for comparrison it will be difficult to determine sex for the unexperienced hobbyist. It will also prove to be more difficult with younger fish rather than more mature fish.

For sexually monomorphic fish species (females and males look alike) Venting is the most accurate form of sex determination.

Answer 2

Fish don't vent. They have one though through which they excrete.

Answer 3

Allong with feces.
