Bristlenose Plec Breeding

To celebrate Easter Harri and Bertie have decided to provide some eggs of their own.
I've had a quick rummage around the internet for some information, and I was hoping that you guys could offer some advice.
Harri is the standard bristlenose (dark with light markings), and Bertie is yellow (not albino). What colour are the offspring likely to be?
As they share a tank with lemon and black neon tetras I'm guessing that I will not end up with any fry if I let nature take its course. I've read about removing the wood with the eggs attached, and transferring it into a smaller tank (along with some tank water) to hatch the eggs. Does anyone have any experience of doing this? Any handy hints?
I've got a few days to decide what to do, and any advice will be appreciated.

Exciting times.   Some more plants will help fry hide.  If you do decide to move the eggs to another tank take the parents along as from what I've read the male will usually sit on them.

They will breed again.  If you want to raise a brood you can look at doing it in a separate tank later and leave these ones for now?

As for colour I'd assume genetic principles would apply.  Without knowing the parents genetic backgrounds it'd be impossible to make an accurate prediction especially if the yellow and standard are different species.  Skin colour usually mixes using Mendel squares.  So you can possibly make a hopeful prediction that the fry will end up predominantly lighter standards with pale yellow markings.  Then possibly some dark orange ones with the markings.

Very exciting development indeed! I think you've made a wise choice, at least this time round. Fingers crossed for a successful outcome.
 

Yay!  Just out of curiosity what pH is your water at?

All the eggs have gone. 
Bertie was still guarding the nest area, but when he moved to get some food I couldn't see anything in the nest. Could he have eaten all the eggs? Could they have all hatched on the same day? And digested the egg sacs since 10.30 last night?

Can't see anything lot of plants, wood, leaf litter, etc. in the tank.

At least you know they're willing and ready.    A spare 60 l would probably be enough to breed them alone.

I think it's possible that I'm a complete doofus. 
I don't have any objective evidence for this, but my theory is that Bertie ate the eggs because I turned the tank lights on and frightened him. That tank doesn't have a dimmer on the lights as they are quite bright fluorescent tubes. Both Bertie and Harri tend to scoot off under the wood pile when the lights go on, and this hasn't really been a huge issue before because they come back out after about 15 minutes. Unfortunately the eggs were laid in a hollow on the front of a piece of wood, around half way up. This meant it was closer to the lights, and further away from the heaviest planting.
When I'm absolutely sure there are no survivors from the eggs I think I'll need to put more wood in the tank, perhaps a small terracotta pot or something, and get another set of lights in there that can be dimmed, so the dim lights can come on before the main tank lights.
I guess we live and learn.

Blue lights on a timer sound like a good idea for this tank. Thanks @Sue, I'll get some and sort the tank out.
