My Beautiful Angel is being harassed!

[CeaWitch]

My pride and joy in my 55 is my Koi angel. I've had her for 2 weeks, and all was well until the last 3 days. She is the most expensive fish I've ever bought, but I just had to have her. I had already added a small black angel as sort of a test to see how it would do in my tank. When I put her in, there was the black angel, 4 praecox (2 pairs), an opaline gourami (moved from my 29), a rainbow shark (also moved), 4 corys, and 2 columbian tetras (who school with the rainbows, they seem to think they are the same!). The koi is bigger than 50 cent size, with long fins. All was just fine, then I added 2 rosy barbs. My fish guy knows I try to plan around the koi, and said the rosies would be fine. Now all of a sudden, some rainbows and 1 rosy seem to be nipping at my Queenie! Not constantly, but enough to drive me crazy, and worry me. Is there anything I can do? she is much larger than them..but seems to stay in her favorite corner most of the time. One funny thing, the small angel seems to try and take care of the big one, and stays with her a lot. They don't nip at the small one. Any advice would be very much appreciated!

I would return the barbs and see where it goes from there.

My Rosy barbs were very hungry fish. They also picked at my thin plants a lot. When they were not doing this, they were chasing each other.

Either keep them in a bigger school, or move someone.
