angel tank changes- again

Something is happy in my angelfish tank. This anubias is flowering!

Some of the others have new shoots- I can't quite tell yet if this one is going to be a flower spathe, or just a new leaf.

Mermaid weed is rapidly shedding the old, original leaves now, and new ones growing out on the ends of the stems. They all look disappointingly smaller, though. I don't know if will grow out to similar size or stay so small.

My male angelfish Skye is moving out.

The female has been attacking him with more and more force. I've watched it several times now- he tips his chin up, showing her his belly, backing away and sliding down until he's in a corner or behind a chunk of wood out of sight. She sits in the center of the tank and swings to strike immediately if he came out, planing her body horizontal and hitting him with such force I can hear it outside the tank.

I also heard a lot of dull knocking or clicking kind of noises, I thought it was an odd sound coming from the equipment, but checked it all and found nothing amiss. Then I noticed I heard the noise when the angels where threatening each other, jerking little shakes with pelvic fins spread in a v, or darting and biting. I looked online and found other angelfish keepers have reported hearing such noises when the fish are "agitated". Well. I think it was M. Beautiful making the noise as a threat to Skye.

Since I moved Skye out of the tank. I have not heard the sound again. M. Beautiful looks kind of at a loss, sitting around, dull of color- I don't know if she actually misses him, how could she, after protesting his presence in the tank so strongly? Probably she was stressed out by the moves I made in the tank to catch Skye, although I did so carefully, using a plastic box not the net (to avoid damaging his fin extensions). I'm considering moving back to my old plan, getting dither fish again (sigh).
