I have the regular Kribensis pulcher in my 75g and they are fun to watch to parent the fry. But they only guard them up to 2 months and abandon them and the fry start to thin out, not sure by predation of the parents or by opportunistic tankmates. At the end, about half a dozen manage to survive which is about the odd expected in nature.
I really like the Kribensis Maliwe and want to stock some in my 125g. But Maliwe is less available, less domesticated and thereby more sensitive to keep from what I read. BTW, your female Kribensis looks like regular pulcher as mine, not Maliwe
