I am confused as they have laid eggs on the syphon before with no problems. The only thing caught was her long tail, so that is why I thought that was the culprit. Also, no signs of sickness. I would not think she was stressed as except for a couple of other much smaller fish the pair were the only ones in the tank (29gl). Also, they have been tank mates from day one. Bought them together (very small), and they have been together for four years. Took about a year for them to pair off though.
I think I am through with the angel fish breeding. Did not buy them for that purpose it just happened (lol).
