Sounds like a reality TV show in there andy! Must be fun to watch.. do your angels do a morning patrol when in spawn? Like frantically swimming the tank looking in every nook and crany for posable threats?

Actually it's real reality TV.
lol
Regarding the pairs, NO, they don't. The reason they don;t is because I have them in a tank by themselves, up high so there is little to nothing going on in front of them to alarm them ( unless they are looking down, they are looking out at the other side of the building), 3/4 of their tank is blocked off so there is no visuals of other fish except when they come to the front of the tanks for food and the slates are towards the rear of the tanks in the protected area. They have no reason to be fearful of a lost spawn except by the "big fish" ( a.k.a. ME
)
What has happened in the past was the fish got used to me pulling their slates so they weren't very surprised by it (I assume.) As I said previously, it's been a while since I had to deal with post spawning aggression. This one pair however, is a mix of 2 fish from different places that were just put together a few days before the spawn and she hadn't been with a mate before when spawning so I can only assume that's why she went bonkers on him. I took the empty slate out of the tank last night and the 2 fish seemed to be better today. No new injuries that I could see. I'll replace the slate closer to when I expect them to spawn again.
I can only guess that because they are so relaxed, they spawn more frequently. It's why I always recommend to people to put their Angel pairs as far away from foot traffic as they can. It makes the fish more comfortable and wanting to breed more.
As for fun to watch, thankfully I have other things to do in there because they are kind of boring to watch when they are so chilled out. I do watch them from a distance so I can see what they are doing but mostly, they are just hanging out, chillin' by the pool with a beer.
lol But once they see the ladder moving, they know it's feeding time so it's "front and center or ya lose out". lol Right now, I do have some F1s that are growing and should be in a larger tank already.
But they are fun to watch because they are lower on the rack and can see me all the time. They are like puppies looking for attention. Any slight movement from me sends them all into a frenzy in the corner of the tank. I don;t know how they all fit in 1 corner but they find a way. Once I get a little further along, I'll do a video of the place as is so you can all see this.
)And these things usually happen when my camera is in the house or the battery is low. 
But the fish do do some crazy things... which is why I love them so. 
) I also can't wait for the A/C - Heat to get back in there so I can do away with so many wires. It makes the airlines stick out in the pics.
