need help sexing angelfish

The girls are the ones wearing lipstick!
In reality Angelfish are hard to sex until they are in breeding condition.
I could give you a long explanation on venting but it really something you have to see for yourself to understand. That said you just have to wait, they know who's a boy and who's a girl

Basically the females tubes look like a "U" and males look like a "V"...

Like Rick said it is VERY hard to tell until you get used to what you need to see... sometimes a female does not have her tube out all the way or even which makes hers look like a "V"

The best way to sex as he said is when they are ready to breed as USUALLY they have their tubes all the way out then... not always though...

The 100% way to sex them.... watch them spawn... and even that is hard to tell because sometimes females will pair and 1 female will pretend to be a male.... sometimes that second female will lay more eggs making the spawn MUCH larger...

If you see a spawn and wait, if they all turn white you either have an inexperience male or 2 females... if there are clearish/pinkish ones... then you have a pair

 

If your wanting them to breed I suggest get several young ones...that way you should end up with at least one pair...when they are breeding you'll know!....they typically chase others away and at times will even guard an area (usually where the eggs will be laid).

 

It does take some time to understand what I was describing.... IF you get lucky enough to watch a spawn you will see if you look at their tubes...

BTW the breeding tubes are located in their "vent" which is their anus.... They can bring them in or drop them down depending on their mood....
