Neon Blues like this Lunar?

Also, getting the female a male will most likely not calm her down as she'll put all her attention on him as soon as he goes in and most likely kill him in days. I know when my male went psycho on my female he killed her and had to live alone for a long time before he could go near another fish let alone another krib. Maybe remove her and re-arrange the tank then add her back in? She'll think she's new(or should do) and will hopefully stop.
Nearly like that. Same blue but absolutely no red in it. That one has slight red lines running vertically.
All I can say re my experiences with Kribs, been keepng them on and off for 25 years, is that I've never had a female do what you describe but good idea to take her out, rearrange and put her and the new male back in. Boromir's tank seems big enough (if its the one in his signature) to cope with a pair or more without too much hassle.
I just mean that if she's more interested in the male and together they're more interested in setting up spawning spot they won't charge around the tank chasing other fish. Maybe if the other fish go to close to the spawning site but they'll stay there rather than chase around the whole tank.
