No need to be upset. From what I read, it sounds like you were mistaking their mating dance as them making a nest. Then the others were correcting you that Angels don't make nests. Adding some pics or better yet, a video might have made things clearer.
I have a single female Bellus now. I'm kinda interested in a pair, but I don't like the look of the male Bellus. The male Watanabe, on the other hand, I think is beautiful.
I might try a Watanabe pair, maybe a trio some day. But my tank is at max capacity, so it will be a long while (hopefully) before a vacancy opens up.
