She is still laying eggs there is another Koi Angelfish see pic below. The one is still laying eggs keeps chasing him away. He is currently on the other side of the tank where they all come at night to rest.
Those are the only two angels in the tank ....had them since they were like dime size. Its a planted tank with bunch of other community fish (neons/cardinals, white tip tetras, glass cats, zebrafish, swordtails, 1 SAE, cherry shrimps, 2 assassin snails, and the 2 Koi Angels.
If there is no male in the tank, two females will often pair up. The result is, of course, eggs that don't hatch. This seems to be a case of a female dumping her eggs, since the other isn't participating.
I have to agree with Bill, when a female is ready to lay her eggs she will and it doesn't matter if there is a male or not. I have also had females that won't let any other fish near her eggs male or not, this happened after her mate had died I put her with different males and she chased them away. Also do you know if you have a male and female for sure, by looking at a picture you can't always tell. If the eggs go white in the next couple of days then they are not fertilized, if you are going to try to raise them in the community tank do not turn off the lights at night as they will be eaten.
Unless you are prepared to feed fry baby brine shrimp, etc. I wouldn't worry about any of this, just observe and learn. Seems these two may me mismatched or they just haven't worked out who's to do what. If the other angel is a male he could be trying to eat the eggs and she could be a better mother than he is a father so she is trying to protect her eggs from him. If they are male and female they will work it out in time - some take time and some are never good parents. Keep an eye on the eggs and if any survive a couple of days and they're not white then you probably have a male/female pair.
Believe me if they're laying eggs now - conditions are evidently good/don't change anything and she/they will be doing this about every two or three weeks again and again and again.....
If you had another tank set up/same water conditions, etc. you'd just remove your intake tube with eggs (replace it with another) and put them into a hatching tank.
