kribensis

Firstly well done, you're becoming quite the accomplished breeder, aren't you?
Female Kribs aren't hard to find, but a problem sometime arises with Kribs - I can't remember which way round it is - (cue Ian, he has a better memory than I do) but I read a paper years ago giving details of Kribensis breeding results with regard to pH of the water.
I think it was the largest proportion of fry turned out to be female when the pH was low, males when the pH was high and somewhere in the middle (neutral) brought a fairly equal amount of males to females.
I have, actually, had similar results with Bettas, Paradise Fish, Apistos and Rams.
Anyway, back to your Kribs, whatever you do will not save every one of the fry - they wouldn't be the easiest of fish to sell, so that isn't so crucial - the parents will 'fight tooth and nail' (but not literally) to protect their fry, but eventually some of the bolder ones get 'wanderlust' and creep away unnoticed. It's then that they are at their most vulnerable - are your Angels in this tank? - They'll make short work of any they find!

Alternatively you could move the eggs into a hatching tank and let bubbles from an airstone pass in their vicinity, but you would then miss the whole 'baby-minding' scenario.

I have tried to move fish into a new tank with their eggs - but only with limited success, although fish like Kribs do have very strong parental tendencies so could be OK.

Why not leave this lot to their own devices and get a tank ready for the next spawning? - It will be quite soon after the initial spawning if all the first brood succomb.

Let us know how things work out, and what you decide to do.
