I have looked at tips online to tell them apart, there is no breeding tube on this one as far as I can see. My other one has a pink tube protruding and is currently rubbing her belly up against a large leaf so I'm guessing she is female and getting ready to lay eggs?
They all have breeding tubes, but when unextended they're inside the body.
What does the tube look like? Sounds like she's female. You'll have to wait until the other extends his/her tube to sex them. It's possible you have two females, as they can spawn without a male (though obviously all eggs will be infertile).
Thanks, this is a pic just as she (I think its a she) was about to rub against the leaf. The other one is not going near the leaf at all just now and can't see any tube they are both scaring the harlequins away if they go near it tho
If she is a she and going to lay how long does the rubbing against the leaf last before eggs are laid?
Well that was an eventful evening, once the eggs were laid it looked like the two angels were fighting at first, then chasing each other and locking lips while both vigorously shaking.....they then both together ate all the eggs!
The one in my first picture is now chasing the female around the tank and she is now hiding at the back of the tank
You may have two females then. It's not uncommon for them to eat their eggs the first few cycles. They're obviously not worth pulling if the unknown angel isn't fertilizing them (due to her being a female or due to him not fertilizing the eggs - depending on what sex it is!).
