Spawning Rainbow Kribs?

I've had Prince Nicholas and Princess Mia (don't ask, my daughter named them) for a grand total of four days. They've settled in extremely well.
They have dug out some substrate from underneath an artificial mango root and the male has been chasing off their tank mates. Are they getting ready to spawn? If they are what would be best to feed the fry on?

It is common with south American cichlids for the parents to eat the eggs the first few times, but I have no idea if the same applies to the African kribs.

Assuming they lay eggs and the parents don't eat them, they will have to defend the eggs against other fish in the tank. Depending on how successful they are, you may or may not have any left to hatch. Eggs hatch in 2 to 3 days and the newly hatched fry are called wrigglers. They are not free swimming at this stage and use the egg sac for food. Once they become free swimming after 7 to 8 days, they will need to be fed. I had success feeding microworms to apistogramma fry; there are several of these tiny worms which can be used - google banana worms, grindle worms etc as well as microworms. They will also eat newly hatched brine shrimp. You can sometimes find baby brine shrimp in the freezer at the fish shop.
If you want to go down the microworm route, you need to start a batch asap. There are lots of sellers; I always got mine from Ebay. You need at least two plastic tubs with lids - and holes punched in the lids; cheap instant porridge and a sachet of yeast. Sand the inside of the tubs to make them rough to help the worms climb up the sides. Make up some instant porridge with water about 1cm deep in the first tub, wait till it cools then sprinkle some yeast over the top. This is optional but the culture works better with yeast. Pour the starter culture on top and wait. Harvest the worms by scraping them off the sides of the tub, being careful not to get any porridge. If you want to deliver them right in front of the fry, add them to a small container of tank water, suck the liquid into a turkey baster and squirt it next to the fry.
The cultures do go off, which is why you need 2 tubs. After a week to 2 weeks, start a second culture with a spoonful of the first. You'll know by the smell when you need to dispose of an old culture.

The unused yeast can be stored in the freezer. It survives well - I have a breadmaker and keep the opened tins of yeast (cheaper than sachets!) frozen.

The wrigglers are a day old now
 

Congratulations!

Just a quick update the fry have been on their swim around the nursery grounds.

The pair have been doing everything right from what I've read up on. Even Prince Nicholas has been helping out.
I've just watched them, what I assume, showing the fry hiding places. Picking a few up at a time and placing then inside a cave.

Ha ha ha, truly is wonderful to watch Simon.

Managed to get a decent picture.

Kribs are reputed to be very good parents. It's always amazing to watch cichlids care for their fry 

Just a quick update.
After a water change this afternoon the female krib had got stuck in an artificial plant.
On seeing the poor soul it was a sorry sight. All her tail fin had been bitten off, I had no choice but to euthanase her.
The male krib has no interest in caring for his offspring. The kids will be put into a hatchery for now and moved as soon as the nursery tank is cycled.

Yup, it's all ready been removed.
We're not sure if she swam in to it and got stuck or if the current took her after she had her tail gone.
