My discus have just laid a shed load of eggs.

I have found the following info:

After all eggs are laid (discus stops swimming in vertical direction), I usually put a stainless wire cage to protect the eggs. This is to prevent both ‘parents’ from consuming their eggs. Add Methylene Blue to prevent eggs from being damaged by fungus. This is what I call the 1st day..

Helping the pairs manage the fry
Usually at day 3 the eggs will start hatching, but the fry will stay attach to the cone. At day 6 or 7, the fry will start to detach themselves from the cone and swim freely. This is the period where we should help ‘parents’ in gathering all fry, so you can get a complete-full batch, by reducing water level to only 25cms or lowest at the above discus upper fins. During this period, you will see that the ‘parents’ can gather all their ‘kids’ and the tiny discus fry will start to consume slime from their parents’ body.

Managing the fry
After day 4 (which means 11 days after 1st egg is laid), where all fry can freely swim, you start to add food. At this stage, I feed them with 1st hatch of brineshrimp or artemia naupli. (4 times a day). If everything goes fine, by day 7 (14-15 days after 1st egg is laid) you can start separating all the fry and put them into a different tank, which this marks the start of the raising process.

Feeding
Fry at day 7 (14-15 days after 1st egg is laid) up to 1 month of age, feed them with artemia or brineshrimp (8 times per day).
When the fry is between 1 month to 1.5 month, feed with artemia (4 times per day) and you can make your own discus burger.
When the fry are above 1.5 month, you can feed discus burger or frozen blood worms (3-4 times per day) and you should have successfully spawned and raised large amounts of fry.

What I want to know is do I still continue to feed the adults twice a day like I've been doing and do a 25% water change every day which I have also been doing? I don't really want to screw this up.

Tank is a 29g with bare bottom and just a sponge filter.

Thanks
 
Continue feeding the adults. You probably should skip the water change until the fry hatch, and then do a smaller (10%) water change.
 
If it's the first time they have spawned then that's what usually happens. Takes a few times for them to get it right.
 
I typically have a three strikes rule on the egg eaters... if I have a great pair who has a fondness for snacking on eggs after that I put a cylinder of plasticized wire mesh over the breeding cone such that they can come within 1/4" of the eggs and circulate water over them but they can't pick at the eggs. This will often solve the issue - when they see the wigglers for a couple days they will often be stimulted to produce the slime coat and will take on their parental duties....

...and some eat the damned fry a couple times.

Be patient.

When there are eggs in the tank I feed carefully and stop as soon as they stop taking it eagerly. I typically stop water changes and just siphon out a little bit with the uneaten food and poop.


Blacking out the sides of the spawning tank (paper, whatever) so they can't see other fish helps keep them calm and can stop the egg eating. Keeping your breeders up high where they don't see all your fishroom stuff happening helps as well.

Final thought - use your least messy foods while eggs are in there or water changes are cut back. FBH is a bloody mess, live white worms or small earthworms or tetra bits seem to reduce the bacteria explosion resulting from frizen/fresh dead foods and fewer water changes.

Hang in there.
