Thanks! I always do some noise reduction and some sharpening and then I sometimes set the white and black point and lighten or darken the image in the curves box. My algae is starting to disintegrate now, though, so the water column is full of specks of algae flotsam. She's displaying to her reflection in the glass and she's right next to it, so anything that's on the glass shows up in the photo, too, so I spent some time bandaiding and cloning out all the little specks. Not anything major.
They spent some time displaying at the same time as last night, but the spawn didn't come off. I had turned the top closed-loop off so I could try to collect eggs, so that might have thrown them. Or, the chromis were gathered around looking for a meal. Or, as might be most likely, the female might just not have been ready again tonight. Try again tomorrow.
