It sure is she is just prepping/cleaning ready for another spawn.Looking at your male in pic here appears to b showing himself to the female this indication is a sign of readiness for spawning good luck.
They do seem to do a lot of displaying and shaking/twitching to one another. Often they will catch the sight of the other across the tank and move towards each other in an arching motion, often bowing heads. I have noticed too sometimes their face/gill plate seems to get slightly darker also.
Noticed the male cleaning the pipe on occasion today, so perhaps in the next day or two they'll try again.
They certainly have a mesmerizing quality, I find myself sitting in front of the tank watching this courtship/pair behavior.
The length of the ventral fins is usually a good indication. I'm guessing your two are between 12 to 18 months. The female is dead keen to spawn. Hope the boy gets his act together soon
Lots of us manage to spend a few hours in front of the tank. We all seem to have the same addiction.
Thirty-five years keeping and breeding discus, and I'm still learning :P
They spawned again this morning (on the cone i provided them), and so far so good. I didn't see them spawn but obviously the male hasn't eaten them this time, and going by the color they appear fertile (only 5 or 6 white ones). I assume if they weren't fertilised they would have started to go white by now?
Ok approx 24hours in a maybe half have got white, the odd fungused too. To my eye I cant see any change in color to other eggs, so not hopeful of any fertilised/wrigglers
