You would be looking at it's side. Find the Dorsal
(Top) fin and look where the fins slope down toward the Tail
fin. Extend an imaginary line along the straight section of
the dorsal fin, back toward the tail. if the line crosses the pass through the Tail
Fin, the fish is most likely to be a FEMALE. If they miss
or just touch
the Tail Fin, then it most likely a MALE.

Andrea
if there anything like Oscars you can't sex them
but someone will be along soon and let you know
usually the female is bigger and rounder in most fish.

what fish have you and we want pics of course. snaps

I believe that in juvenile discus it is almst impossible to tell the difference

In the adult, the easy things to look for is the dorsal fin - in the female it is rounded, in the male it is pointed. The male will be slightly bigger and may have thicker lips too..

Do you have a tank set up Andrea or are you just thinking about what fish to get?

I think Mary (she's away sunning herself in France at the mo) has all Aqua One tanks and rates them highly.

As for the size tank needed for discus, as a rough guide I think you need a tank that is at least 18" deep, and for eacch adult fish you need to have at least 45-50litres so if you are thinking of getting a group it is worth bearing in mind their adult requirements. For a tank to house 12 adult discus you are looking at a tank of about 600litres

as for male and female discus if i remember adult male's will have a slight bump
on his forehead as he matures the females will be more rounder.

hope this helps andrea - and i would say look at all lfs for your tank shop around
look on ebay get the biggest you can afford to give you more scope. good luck.

hey guys! (long time no see) one of the only ways with some cichlids (especialy ones that are visualy difficult to sex ie oscars/ discuss ect) to determin sex would be to actualy hold the fish upside down and look at its "genitals"

i will try to find the forum thread on it. but males will have "oo" and females will have "Oo" lol if that makes sense but the forum i was looking at actualy had a pic to explain it.

Just put a shoe or a handbag in - the female will be 1st to play with it (unless its a confused male)

Least it isnt like snakes and you have to 'poke' them internally to find out

anyway - i know ziltch about discus (except i dont like em Very Happy too hard to fillet0

so i got tis iff a website - hope it helps (still say the handbag method is easier)

One of the biggest question asked of the discus breeder is "how do I
determine the sex of my fish?" There are very few easy identifiable
identifiers in this process. Here, we will discuss the methods used by
some of the top breeders.
In juvenile fish, determining sex is almost impossible. It is only
when they begin to pair off that an opportunity arises to help in the
determination of sex. Juvenile fish, both male and female, have a
rounded dorsal fin, and it is not until they begin to mature that a
difference can be detected. As it is never wise to excessively handle
the fish, close observation is in order to aid the breeder.
In Allnut Enterprises' King Discus Hatchery, for example, it is an
easy process to determine who is who, as we have observed these fish
for a while, and can determine the sex of the pairs we own. This would
be true in any hatchery. But to the uninitiated or casual observer,
this would not be easy to do.


window.google_render_ad();

Some of the identifiers: The male will have thicker lips to aid him
in his fight to protect the female, and will be more aggressive. He
will be larger than the female, his forehead is thicker, and we have
observed that if the discus are a bit shy, the male will have a
tendency to stay between the female and the observer.
The dorsal fin of the male will be pointed, and the female's dorsal
fin will be rounded. Note that in juvenile discus, this is not apparent.
The breeding tube of the female, between the anus and anal fin, is
broader and rounder than the male, and will have a blunt tip. The male,
in turn, has a smaller, sharper breeding tube. Be aware that this is
only evident during spawning, and should be closely observed.
It has been said that the male discus fish will tend to have a less
intense color and more pattern while the female tends to be more
colorful but with lesser pattern. I disagree, because too many
variables are in place here, such as the health of the discus, the
water parameters, and feeding pattern.
In an interesting article by Jeff Richard, he discusses an article
from Diskus Brief, a German publication, which reports a very
successful way of determine sex of a discus by using simple geometry.
Jeff reports, and I quote: "Picture a discus facing to your left ...
you would be looking at its side. Find the Dorsal (Top) and Anal
(bottom) fins and look where the fins slope down toward the Caudal
(tail) fin ... make sure you're looking at the fins after they have
curved back toward the tail. The Dorsal and Anal Fins become (almost)
straight after the fins curve down (or up) toward the Caudal Fin ...
extend an imaginary line along this straight section of the 2 fins back
toward the tail which just touches the Dorsal and Anal Fins past the
Caudal Fin. These two imaginary lines should intersect behind the fish.
The key to sexing the fish is where the lines cross the Caudal fin. If
they pass through the Caudal Fin, the fish is most likely a FEMALE. If
they miss or just touch the Caudal Fin, then most likely it is a MALE."
Thanks, Jeff!
Sexing Discus is difficult at best. The easiest way to do so is to
raise a group of at least six to eight discus, and allow them to pair
off when ready. It is a beautiful sight to see this happen, and makes
the hobby well worthwhile.
